ChangeLog

@ -19,6 +19,9 @@ CVS Code -
New functions search_init_globals and do_replace_loop, changes
to search_init(), do_replace, findnextstr, moved last_search and
last_replace back to nano.c (*shrug*).
- New tab completion code. Used check_wildcard_match, input_tab,
cwd_tab_completion, username_tab_completion from busybox,
hacked them a lot, changes to nanogetstr().
- files.c:
do_writeout()
- Change strcpy to answer to mallocstrcpy.
@ -59,8 +62,8 @@ CVS Code -
into statusbar" bug in odd $TERMs like iris-ansi.
- Changed check to return -2 on "enter" from answer == ""
to answer == def.
- Silly kludge in backspace code to temporarily decrement x
before refreshing to keep the cursor visually aligned.
- Fixed fallthrough code because there was no break. Make much
more sense now.
nanoget_repaint()
- New function, removes about 30 lines of duplicate code in
nanogetstr().
