- Translation updates (see po/ChangeLog for details).
- Fix globals and externs such that nano will compile with
DISABLE_SPELLER (David Benbennick).
- Fix unreasonable fill values by wrapping at length 0 instead
of erroring out, and don't start up if the window size is too
small but fill is set reasonably. Changes to
nano.c:global_init(), window_init(), and handle_sigwinch().
New macro MIN_EDITOR_COLS replaces MIN_FILL_LENGTH
(David Benbennick).
- files.c:
cwd_tab_completion()
- Memory leak fix (David Benbennick).
