CVS code -
+- General:
+ - Convert more ints that hold only TRUE and FALSE values to
+ bools. (DLR)
+ - Consolidate the code for finding a shortcut in a shortcut
+ list, the code for finding a toogle in a toggle list, and
+ the code for doing both of those and interpreting mouse clicks
+ in the edit window. Also move the code for do_mouse() to
+ get_edit_mouse() and tweak it to properly handle cases where a
+ shortcut isn't clicked. New functions get_shortcut(),
+ get_toggle(), get_edit_input(), and get_edit_mouse(); changes
+ to do_browser(), do_justify(), do_help(), and main(). (DLR)
- rcfile.c:
parse_rcfile()
- Add missing brackets around an if statement block so that
parsing the numeric argument after "tabsize" works properly
again. (DLR, found by Mike Frysinger)
+- winio.c:
+ get_mouseinput()
+ - Consolidate two if statements to increase efficiency. (DLR)
+ do_yesno()
+ - Don't bother assigning the value of get_mouseinput() to
+ anything. Since allow_shortcuts is FALSE, its return value
+ will always be FALSE. (DLR)
