@ -110,6 +110,14 @@ CVS code -
- Make sure all rcfile error messages are capitalized, for
consistency. (DLR)
- winio.c:
get_verbatim_kbinput()
- Fix a silly memory corruption bug that would occur when trying
to read a sequence of more than one key verbatim. (DLR)
get_accepted_kbinput()
Handle Ctrl-{ to Ctrl-~ correctly, and drop support for
converting Esc ` to Esc Space, since making Meta-[key]
correspond to Ctrl-[key] in all cases is inconsistent due to
the different natures of Contol and Meta key sequences. (DLR)
do_first_line()
- Call edit_update() with TOP instead of CENTER; both do the
same thing, but it works faster with TOP. (DLR)
