/*
|
|
* Edit option information. Historically, if you set a boolean or numeric
|
|
* edit option value to its "default" value, it didn't show up in the :set
|
|
* display, i.e. it wasn't considered "changed". String edit options would
|
|
* show up as changed, regardless. We maintain a parallel set of values
|
|
* which are the default values and never consider an edit option changed
|
|
* if it was reset to the default value.
|
|
*
|
|
* Macros to retrieve boolean, integral and string option values, and to
|
|
* set, clear and test boolean option values. Some options (secure, lines,
|
|
* columns, terminal type) are global in scope, and are therefore stored
|
|
* in the global area. The offset in the global options array is stored
|
|
* in the screen's value field. This is set up when the options are first
|
|
* initialized.
