display: keep the help items aligned, by not writing too many characters

Browse Source 
Only for the last item at the end of each of the two help lines there
are sometimes a few extra columns available.  Do not use these extra
columns also for the other help items, because apparently, when wmove()
lands in the second column of a double-width character, it does not
wipe out this character (replacing it with a space) but goes to the
next column instead, causing a misalignment of the text.

This fixes https://savannah.gnu.org/bugs/?57994.

Bug existed since version 1.3.12, commit e806ab84.
