In a non-UTF8 build, mbwidth() returns always 1, so it is pointless
to call that function and compare its result to zero then.
Also, don't bother special-casing the function for a non-UTF8 locale.
When there are fewer than four menu items, act as if there are four:
make their clickable width half the width of the screen.
Until now, when there were two menu items, their clickable width would
be the full width of the screen, which was overwide. But when there
was just one menu item, its clickable width would suddenly be as small
as when the menu had the maximum number of items (12 for an 80-column
screen). This was odd.
Also, slightly simplify another computation.
The first_sc_for() function is somewhat costly, so avoid calling it
when it is not necessary.
Most menus have either so many entries that unbinding some keys does
not reduce the number of shown entries, or they have so few entries
that each entry already has space enough and will not profit from
having more room available. But the WriteOut menu is an edge case.
Most translators don't use --tempfile and translate the key tags for
the WriteOut menu making use of all 17 positions that are available
for each of them. This makes that when --tempfile is used, some of
those tags get truncated. This is not so bad, because --tempfile is
normally not used. But when it isn't used (when the discardbuffer
function isn't bound), the WriteOut menu should make full use of the
available width to avoid truncating any translated tags.
In this way the keycode cannot be unbound from the 'indent' function,
so pressing <Tab> on a marked region will always indent the region.
This fixes https://savannah.gnu.org/bugs/?56960.
Bug existed since the "tabbing" of a marked region was introduced,
in version 2.9.2, commit 09958ebd.
The 'tabgives' command is syntax-specific and should be followed by a
string containing the character(s) that a single press of the <Tab> key
should produce -- most likely a single TAB or a small bunch of spaces,
but any string is allowed. This overrides the 'tabstospaces' option.
When one wants to make sure <Tab> inserts always four spaces and never
a TAB when editing a Python file, one could add to one's nanorc:
extendsyntax python tabgives " "
where there are four spaces between the quotes. And when one wants
to ensure, when editing a Makefile, that <Tab> always inserts a TAB
and never spaces, independent of what tabstospaces is set to, one
could add to one's nanorc:
extendsyntax makefile tabgives " "
where there is a literal TAB character between the quotes.

As printf() is not UTF8-aware, we have to determine ourselves how many
columns each short and long flag take up and add the required number of
spaces (not tabs, because their size is not fixed) to fill things up.
This fixes https://savannah.gnu.org/bugs/?56928.
Bug existed since version 4.3, commit 2f169107.
When the user specified an absolute path... it is NOT relative to the
current working directory.
