complicated for a feature freeze.
- Disable VSTOP keystroke. Stops people accidentally locking up
nano (suggested by David Benbennick).
+ - Pluralize messages with ngettext() where needed. (David
+ Benbennick)
+ - Update nano.1 and nano.1.html to show that nano now does an
+ emergency save on receiving SIGHUP or SIGTERM. (DLR)
+ - Don't include "nowrap" in the long options if
+ DISABLE_WRAPPING is defined. (DLR)
+- files.c:
+ read_file()
+ - Minor efficiency fixes, some of which fit in with the change
+ to ngettext() usage mentioned above. (David Benbennick)
+ do_browser()
+ - Make sure the value of path is mallocstrcpy()ed into retval
+ and not just assigned to it, to avoid memory corruption
+ problems. (DLR)
+- nano.c:
+ justify_format()
+ - Make sure the double space maintained after sentence-ending
+ punctuation is done when that punctuation is immediately
+ followed by a bracket-type character, so justifying e.g.
+ sentences in parentheses works properly. (David Benbennick)
+ handle_hup()
+ - Renamed handle_hupterm() to show that it now handles SIGTERM
+ as well as SIGHUP. (DLR)
+ signal_init()
+ - Do an emergency save on receiving either SIGHUP or SIGTERM,
+ not just SIGHUP. (David Benbennick)
+ main()
+ - Fix a problem where control key commands were printed
+ literally instead of interpreted after a failed search of a
+ one-line file. (David Benbennick)
+- proto.h:
+ handle_hup()
+ - Renamed handle_hupterm(); see above for why. (DLR)
+- winio.c:
+ edit_add()
+ - Fix a potential infinite loop occurring with certain
+ zero-length regexes. (David Benbennick)
