if ~/.nano_history is unwritable, and prevent ~/.nano_history
from being completely overwritten by save_history() if it's
unreadable but writable. (David Benbennick)
+ - Only unset KEEP_CUTBUFFER in main() when we do something other
+ than cut text in the main input loop, instead of unsetting it
+ all over the place (which, as written, didn't handle cases
+ like a cut followed by M-Space properly). Also, instead of
+ checking for keyhandled's not being set inside the for loops,
+ do it in if blocks surrounding the for loops to increase
+ efficiency. (David Benbennick) DLR: Also unset KEEP_CUTBUFFER
+ if we hit a shortcut key other than the one for cutting text.
+ - Make it so a marked cut immediately followed by an unmarked
+ cut tacks the latter's text onto the end of the former's text
+ instead of putting it on a new line, as Pico does. (DLR)
+ - Convert instances of "(char *)nrealloc()" to the macro
+ charealloc(), which does the same thing. (DLR)
+- cut.c:
+ do_cut_text()
+ - Tweak where KEEP_CUTBUFFER is set so that a marked cut
+ immediately followed by an unmarked cut preserves the
+ cutbuffer between the two. (David Benbennick) DLR: Also
+ properly set KEEP_CUTBUFFER in tiny mode.
+ do_uncut_text()
+ - If we're about to uncut on the magicline, always make a new
+ magicline in advance, as Pico does. (DLR)
- global.c:
shortcut_init()
- Simplify the #ifdef used to enable file insertion in view mode

- nano.h:
- Simplify #ifdefs relating to HAVE_STRCASECMP and
HAVE_STRNCASECMP. (David Benbennick)
+- search.c:
+ goto_abort()
+ - Removed, with all instances replaced with display_main_list(),
+ since with the removal of all the scattered calls to
+ SET(KEEP_CUTBUFFER), that function was all that was left of
+ it. (DLR)
+ do_find_bracket()
+ - If a matching bracket wasn't found, call update_line() after
+ setting current and current_x back to their original values,
+ in case current_x's original value is greater than the width
+ of the screen. (DLR)
- configure.ac:
- Enable autodetection of broken regexec(). (DLR) Re-added
regex.h check to ensure compile under Debian w/autoconf 1.6.
