put the command line options in a more consistent (i. e. mostly
put the command line options in a more consistent (i.e. mostly
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.

.SH NOTES
Nano will try to dump the buffer into an emergency file in some cases.
Mainly, this will happen if Nano receives a SIGHUP or runs out of
memory, when it will write the buffer into a file named "nano.save" if
the buffer didn't have a name already, or will add a ".save" suffix to
the current filename. If an emergency file with that name already exists
in the current directory, ".save" and a number (e.g. ".save.1") will be
suffixed to the current filename in order to make it unique. In
multibuffer mode, nano will write all the open buffers to the respective
emergency files.
