alphabetical) order in nano, put the long options in a more
consistent order in rcfile.c and nanorc.sample, don't include
rcfile options if their equivalent command line options are
disabled, and remove obsolete relative option from
nanorc.sample. (DLR)
- Removed much unnecessary parts to the color code and reworks
some of the color display (David Benbennick).
- Change "File Name to Append/Prepend" to "File Name to
Append/Prepend to". The original prompt could confusingly
imply that we are appending/prepending another file to the
current file, when we are actually appending/prepending the
current file to another file. (DLR)
- Put nano.1, nano.1.html, and nano.texi up to date. (DLR)
- Typo fixes for the ChangeLog. (David Benbennick)
- Put nano.1, nano.1.html, and nano.texi up to date, and fix a
few inconsistencies in them. (DLR)
- Typo fixes for the ChangeLog. (David Benbennick and DLR)
- Complete rewrite of justification code to fix some bugs and
improve its functionality. (David Benbennick)
- If a variable isn't going to be used in tiny mode, #define it
out when possible. (David Benbennick)
- Major reworking of the cutting/screen-updating code in cut.c,
some functions in utils.c, the cursor placement code in
winio.c, and many, many other areas to increase efficiency.
(David Benbennick)
- Rework handling of prompts when there's a list of partial
filename matches on the screen: remove kludgy case-by-case
handling (which didn't even handle every case), and have
statusq() handle it directly for all cases. (David Benbennick
and DLR)
- Fix some warnings and errors that show up when using gcc's
-pedantic option. (DLR)
- Add a comment to nanorc.sample warning that an out-of-range
negative value for fill can make nano die complaining that
the screen is too small (which may not be immediately
obvious. (DLR)
- There were some opendir() calls in files.c without
corresponding closedir() calls; add them. (DLR)
- Move align() and null_at() from nano.c to utils.c, and move
the openfilestruct handling functions from nano.c to files.c.

- In color.c, start the "#ifdef ENABLE_COLOR" block after
including all the header files, as rcfile.c does; this fixes
a warning about ANSI C'S inability to handle blank files.
