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.
The functions read() and fwrite() take size_t, not ssize_t.
And line numbers in the file should be displayed as a long type instead
of an int, since the effective type of ssize_t is not int, but long.
It can be activated with --linenumbers on the command line or with
'set linenumbers' in a nanorc file, and it can be toggled with M-#.

This allows the user to specify which other characters, besides the
default alphanumeric ones, should be considered as part of a word, so
that word operations like Ctrl+Left and Ctrl+Right will pass them by.
Using this option overrides the option --wordbounds.
This fulfills https://savannah.gnu.org/bugs/?47283.
It is easy to type beside the comma key and hit instead "m" or ".", so
accept also these as a separator between line and column number. And
when being generous anyway, also accept space, slash and semicolon.
This fulfills https://savannah.gnu.org/bugs/?48305.

If during startup there are multiple error messages, currently only the
last one remains and can be read. To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.
This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.
