and spacing improvements. (David Benbennick)
- Make more functions use const variables when possible. (David
Benbennick)
- Add Carl Drinkwater's backup file option (-B or --backup on the
command line, M-B in nano's global shortcuts). If the original
file is unchanged from when it was loaded, it is backed up to
filename~; if the original file has been changed or deleted
since it was originally loaded, it isn't backed up. The backup
file retains the permissions, owner/group, and
access/modification times of the original file. This option is
disabled when --enable-tiny is used. It will not back up
temporary files. Minor fixes to it by David Benbennick and
DLR. Changes to open_file(), add_open_file(),
load_open_file(), write_file(), and do_writeout().
- Add \n's to the ends of "filename is %s" debugging strings.
(Carl Drinkwater)
- Add the long option --quotestr as an alternative for -Q, and
--regexp as an alternative for -R; they were listed in nano's
usage information, but weren't actually in nano. Also, display
"-?" as an alternative for "-h" in nano's usage information,
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)
- 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)

do_writeout():
- Fix problem with formatstr's being defined as NULL when
--enable-tiny is used. Since formatstr isn't ever used in tiny
mode, don't bother even creating the variable. (David
Benbennick and DLR)
append_slash_if_dir(), input_tab():
- Changed a variable name: lastWasTab -> lastwastab. (DLR)
- global.c:
shortcut_init()
free_toggles():
- Only include if we're not using tiny mode. (David Benbennick)
toggle_init():
- Remove global entries for search toggles, as they aren't really
global. (DLR)
- Don't reinititialize the toggles if they've already been
initialized; it's unnecessary and even causes a segfault in
do_toggle() if Pico emulation mode is the toggle in question.
Don't free the toggles here, either; it's unnecessary after the
above change. (David Benbennick)

do_int_spell(), do_alt_spell():

and restore it afterward. (DLR)
do_toggle():
- Since the search mode toggles aren't global anymore, we don't
need to explicitly block them here anymore (which will end up
blocking the global backup mode toggle, which is the same as
the backwards search toggle). (DLR)

with it, instead of calling clear_filename() in two places.

.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
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.
