routine to get the current user's home directory into the new
function get_homedir(), and use it where necessary. Also add
a few miscellaneous tweaks.
- Overhaul the rcfile parsing code to make it simpler and more
accurate, remove now-redundant checks from the color code,
change the COLOR_SYNTAX toggle to the NO_COLOR_SYMTAX toggle,
and improve various debugging messsages. Changes to
set_colorpairs(), do_colorinit(), parse_next_word(),
parse_argument(), colortoint(), parse_next_regex(),
parse_syntax(), parse_colors(), parse_rcfile(), do_rcfile(),
etc. (David Benbennick) DLR: Rename colortoint() to
color_to_int(), and add a few miscellaneous tweaks.
- cut.c:
do_cut_text()
- If keep_cutbuffer is FALSE, only blow away the text in the
