Move the nine #undef's common to all qt_*.cpp sources into qt_pre.h.
Make "hack.h" usage consistent; always enclose withing 'extern "C {'
and '}' even though only some of the sources care.
An earlier tweak worked to prevent unnecessary line wrapping
for ^X output in a menu, but #enhance and '+' both had problems
with their last column. This seems to work better but is still
based on thrashing about rather than knowledge of how things are
supposed to operate.
The change to use fixed-width fonts for menus wasn't working
optimally because the font got changed after menu construction
had measured the necessary width and height amounts. ^X output,
which uses a menu instead of a text window for tty's benefit
(probably curses too; I don't remember), had a couple of lines
which were wrapping unnecessarily.
This fix avoids that, but the extra '+20' shouldn't be needed.
Unfortunately lines in menus are effectively double-spaced, which
looks bad, and I've no idea how to fix that.
Qt menus have [ok][cancel][all][none][other stuff] buttons across
the top but it was disabling [cancel] for inventory viewing and
other pick-none menus. Enable that so that [cancel] is a viable
alternative to typing ESC or clicking on [ok] for dismissing the
menu without picking anything.
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.
