When copying a string, source and destination may not be equal --
complain loudly when they are, instead of failing to free memory.
Also, instead of freeing the destination string and then allocating
it afresh, just reallocate it -- that should be slightly quicker.
Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab. The intended tab size (for keeping most lines
within 80 columns) is now four.
When unindenting/uncommenting affected the bottom line of the marked
region, keep affecting this line also during subsequent consecutive
indenting/commenting.
This fixes https://savannah.gnu.org/bugs/?52718.
If the marked region ends at the start of a line, do not include that
line in the indenting/undenting or commenting/uncommenting. This is
closer to what the eye would expect.
The pointer not being NULL is enough indication that the mark is set.
Also, rename the pointer from 'mark_begin' to simply 'mark', since
the former is kind of pleonastic.
When not finding a .nanorc file in the user's home directory, nano will
look for a nanorc file in $XDG_CONFIG_HOME and in the ~/.config/nano/
fallback directory. And when not finding a .nano/ subdir in the user's
home directory, nano will look for (or create) the history files in
$XDG_DATA_HOME or in the ~/.local/share/nano/ fallback directory.
This is a partial implementation of the XDG Base Directory Specification:
https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html,
for the purpose of reducing the clutter in a user's home directory, and
to make it easier to back up just the configuration files.

Call something a buffer when it refers to a linked list of linestructs,
and call something a linestruct when it is a struct that describes a
single line.
The interval 2013-2017 for the Free Software Foundation is valid
because in those years there were releases with changes by either
Chris or David, and the GNU maintainers guide advises to mention
a new year in all files of a package, not just in the ones that
actually changed, and be done with it for the rest of the year.
That is: remove the special treatment of BOW anchors, and instead make
regexes match against the whole line instead of against an artificially
shortened one, because the latter method creates ghost matches: matches
at the starting point of the search that aren't really matches when seen
in the context of the whole line.
This fixes https://savannah.gnu.org/bugs/?50030.
A search should start at the place of the cursor, not one step beyond,
so that the non-word boundary between the current character and the next
will be found. Starting one step beyond the current character, as was
done until now, would find the non-word boundary between the next and
the overnext character as the first one.
The fsfromline() function is mostly used by the undo functions, which
are not present in the tiny version. It is also used by the comment/
uncomment feature, but this feature cannot be enabled when --enable-tiny
is in effect.
Convert digits() to take a ssize_t instead of an int, since it's
used on ssize_t line numbers. And properly use the long modifier
when displaying a line number.
Also, conditionalize the digits() prototype.
