Most full paths are needed only temporarily and will be freed within
milliseconds. Only 'full_operating_dir' and 'backup_dir' continue to
exist for the whole current session. Any partition, too, will soon be
unpartitioned, so the extra reallocation is just a waste of time.
That is: elide a second test from the most travelled path: a valid
character. This adds a second call of mblen() when parse_mbchar()
is called on a terminating zero, but that should never happen.
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.
An added magic linefeed should be removed again /before/ restoring
the x position, as the latter needs to be calculated from the real
last line of the region.

When wanting to debug something, it is far more useful
to temporarily insert lines like:
statusline(ALERT, "name = %i", variable);
It provides instant feedback, and it slows things down,
so you can kind of see what happens.
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.
(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy. The compiler will probably be able to elide it.)
When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found. Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that. By default the function is bound to the ^] keystroke.

Modern VTE-based terminals now produce codes for those keys and
no longer swallow them when nano is active.
