94b8ec0021 Partially add back in "support REP (repeat) escape sequence"
Add the functionality back in for xterm compatibility, but do not expose the
capability in st.info (yet).

Some notes:

It was reverted because it caused some issues with ncurses in some
configurations, namely when using BSD padding (--enable-bsdpad, BSD_TPUTS) in
ncurses it caused issues with repeating digits.

A fix has been upstreamed in ncurses since snapshot 20200523. The fix is also
backported to OpenBSD -current.

475a0a36cb Revert "support REP (repeat) escape sequence"
This reverts commit e8392b282c.

There is currently a bug in older ncurses versions (like on OpenBSD) where a
fix for a bug with REP is not backported yet. Most likely in tty/tty_update.c:

Noticed while using lynx (which uses ncurses/curses).
To reproduce using lynx: echo "Z0000000" | lynx -stdin

or using the program:

int
main(void)
{
	WINDOW *win;
	win = initscr();

	printw("Z0000000");

	refresh();

	sleep(5);

	return 0;
}

This prints "ZZZZZZZ" (incorrectly).

e8392b282c support REP (repeat) escape sequence
The sequence \e[Nb prints the last printed char N (more) times if it's
printable, and it's ignored after newline or other control chars.

This is Ecma-048/ANSI-X3.6 sequence and not DEC VT. It's supported by
xterm, and ncurses uses it when possible, e.g. when TERM is xterm* (and
with this commit also st*).

xterm supports only codepoints<=255, possibly due to internal limits.
We support any value/codepoint which was placed in a cell.

To test:
- tput rep 65 4 -> prints 'AAAA'
- printf "\342\225\246\033[4b" -> prints U+2566 1+4 times.

019449a7e6 Add terminfo entries for backspace mode
St used to use backspace as BS until the commit 230d0c8, but due
to general lack of knowledge of lusers, we moved to the most common
configuration in linux to avoid answering the same question 3 times
per month. With the most common configuration we have a backspace
that returns a DEL, and we have a Delete key that doesn't return a
DEL character neither a BS.

When dealing with devices connected using a serial line (or even
with Plan9) it is more common Backspace as BS and Delete as DEL. For
this reason, st is not always the best tool when you talk with a
serial device.

This patch adds new terminfo entries for Backspace as BS and Delete
as DEL. A patch for confg.h is also added, to make easier switch
between both configurations.

The tmux terminfo extensions Ss and Se are currently specified as
booleans in `st.info`. They should be strings. See

487bbb24d0 Update kdch1 definition to three octal digits.
ncurses wasn't able to detect the delete-character key as KEY_DC.  This
patch fixes that.

kdch1 was defined as "\0177", but terminfo(5) states:
	... characters may be given as three octal digits after a \.

The delete-character key is correctly defined in config.def.h.

1b514048b2 Let curses do the dirty work for flash
Use the terminfo delay syntax ($<x>) in our flash capability to avoid
hardcoding a fixed delay in redraw() when called from tsetmode() with
DECSCNM.
We need to turn on the npc capability so that delays are made with
xon/xoff instead of padding characters.

dcfe505d3c Use G1 for alternate charset
St has enacs, which must be printed if a program requires to use
the alternate charset (graphic charset), that in st case was to
select charset graphic for G1, but it was not useful
at all because smacs and rmacs were always redefining the value
of G0.

821a6e00a5 Remove ul capability
This capability indicates that underscore '_' overstrike current
letter under the cursor. It means that you can generate a
underline 'b' using 'b^H_', because it writes a 'b' then backward
one characther and then overstrike '_'. St has not such behaviour,
so it is an error to have this capability.

c46d929fe1 Fix Backspace and Delete characters
Backspace key must generate the backspace character (\010) and
Delete key must generate the delete character (\0177). In
some systems the kernel configuration for erasing previous character
is \0177, so some programs (for example cat, ed, mail, ...), can not
understand the correct meaning of backspace. In this cases it is only
needed this command:

rmul means "exit underline mode", so a full reset of all
the attributes is not the correct way of exiting from

4579693818 Add terminfo definitions for terminals with meta key
Some programs don't check the value of km and use smm and rmm
capabilites, and they cause the terminal change to meta enabled
mode even in cases where is not desirable.

Allmost all people is using the terminal waiting that meta sends
escape, so rmm and smm are not needed. If someone needs meta
sets 8 bit he can use the correct terminfo definition in TERM.

d5994b43ca Add support for End key
- Shift + End : Delete until end of line.
    - Control + End : Delete until end of screen.

When  the End  key is  pressed  without any  modifier is  not generated  the
correct sequence for it  (going to the end of the  screen), because the size
of the  terminal is not known,  so it is  not possible write a  sequence for
this purpouse.

3c99be68e8 Add support for insert key
Insert key stands for a key which allows enter or leaves insert mode, so let
it generates the correct sequence to change between these modes:

   - Insert: Enter in insert mode.
   - Shift + Insert: Leave insert mode (replace mode).
   - Control + Insert: Insert a blank line.

Like Shift + Insert also paste text, if a user want this feature be full
functional he has to modify such shortcut.

620e3bb39e Add missed key definitions
This patch adds the keys for the keypad (in both modes, application mode or
ansi mode) and function keys. It uses the same convention than xterm and
instead of using the XK_Fxx values it generates them using F1-F12 and
modifiers. For example:

   F1 -> ^[OP
   F1 + Shift = F13 -> ^[[1;2P
   F1 + Control = F25 -> ^[[1;5P
   F1 + Mod2 = F37 -> ^[[1;6P
   F1 + Mod1 = F49 -> ^[[1;3P
   F1 + Mod3 = F61 -> ^[[1;4P

It is also important notice than the terminfo capability kIC (shifted insert
key) only can be generated using the keypad keyboard, because the shorcut
for selection paste is using the same combination.

After this path the number of elements in the Key array becomes high, and
maybe a sequencial search is not enough efficient now.

44597b359e Add control and meta combinations for arrow keys
Since there isn't any terminfo capability for control and meta modifiers for
arrows keys it is necessary use the same that almost terminal emulators use,
because there are a lot of programs which have these codes hardcoded.

This cause also that shift combinations are also changed, but in this case
this is not a problem since there are terminfo capabilities for them. After
this patch shift-up and shift-down continue not working in emacs with
TERM=st, but they work with TERM=xterm, so it is possible some other changes
are necessary in the terminfo entry.

3b16695f4e Fix arrow keys terminfo capabilities
Usually the arrow keys generate the ANSI sequence which terminal will
understand like a movement, so it is not necessary any dealing for them, the
program can not know if the sequence is generate for a echo key or directly
from the program. If you need really know if the key was pressed then you
need activate the keypad mode where the keys will generate a special code
for each keypad key.

The terminfo capabilities kcub1, kcud1, kcuf1 and kcuu1 are used for this
keypad code, not for the sequence generate in the ansi mode.

69ee3ba3a7 Fix keypad mode and cursor mode
Keypad mode is used for detecting when keys in the auxiliary keypad are
pressed, while cursor mode is used for detecting when a cursor is pressed,
but they are different modes.

St was mixing both modes and DECPAM and DECPNM modified the cursor mode, and
this was incorrect.

cfefa054e8 Patch from Roberto Vargas. »Add initialization strings in terminfo«
Taken from the description:

When tput init is executed the list of task performed are (taken from
terminfo(5)):

              run the program
                     iprog

              output is1 is2

              set the margins using
                     mgc, smgl and smgr

              set tabs using
                     tbc and hts

              print the file
                     if

              and finally
                     output is3.

When reset is executed, a more stronger initialization process is performed,
so the terminal can return from an unknown state. rs1, rs2 and rs3 are used
in this case instead of
using is1, is2 and is3.

This patch makes is2 = rs2, resets insert mode and set normal keypad
mode. For rs1 it performs a full initilization using ^[c.
