* be broken. 2) If lines should not be broken and filled, just copy up to
* end of comment. 3) If lines should be filled, then scan thru input_buffer
* copying characters to com_buf. Remember where the last blank, tab, or
* newline was. When line is filled, print up to last blank and continue
* copying.

* FUNCTION: Implements the reduce part of the parsing algorithm
*
* ALGORITHM: The following reductions are done. Reductions are repeated until
* no more are possible.
*
* Old TOS New TOS <stmt> <stmt> <stmtl> <stmtl> <stmt> <stmtl> do
* <stmt> "dostmt" if <stmt> "ifstmt" switch <stmt> <stmt> decl
* <stmt> <stmt> "ifelse" <stmt> <stmt> for <stmt> <stmt> while
* <stmt> <stmt> "dostmt" while <stmt>
*
* On each reduction, ps.i_l_follow (the indentation for the following line) is
* set to the indentation level associated with the old TOS.
*
* PARAMETERS: None
*
* RETURNS: Nothing
*
* GLOBALS: ps.cstk ps.i_l_follow = ps.il ps.p_stack = ps.tos =
*
* CALLS: None
*
* CALLED BY: parse
*
* HISTORY: initial coding November 1976 D A Willcox of CAC
