This greatly improves the '?' choice when using the '#' prefix
to select an extended command. It isn't perfect, because the
<text><spaces><more text> layout (using spaces to pad the first
column so that the second one lines up) produces at least one
line where <more text> is so long that it wraps, and instead of
| <text><spaces><start of more text>
| <blank><spaces><rest of more text>
that selectable menu entries have, the continuation is
| <text><spaces><start of more text>
|<rest of more text>
(made slightly worse by the fact that <text> is indented a little
and <rest...> isn't.
This affects the aesthetics of all NHW_MENU windows, not just the
one that desparately needed help. Maybe the core should send some
hint on a menu or text window by menu or text window basis about
whether or not fixed-width font is preferable to variable one.
