Menus with wide header or separator lines were rendered wide enough
to avoid wrapping those lines, but ones with narrow header/separators
and wide selectable entries were limited to half the display even
though lots of lines that would fit with full width were being wrapped.
Change the latter behavior.
Menus are right justified with the edge of the map when narrower than
it, left justified otherwise, and if the display is wider than the map,
they'll extend beyond its right edge. (That hasn't actually changed;
it's just that left-justification is more likely now that menus will
be wide enough to show wide inventory lines without wrapping.)
Get rid of my ridiculous hack to force wider menu for the 'symset'
and 'roguesymset' sub-menus of 'O' since it's no longer useful.
There's still room for improvement. If any lines need to be wrapped
despite using the full width, or perhaps are just a lot wider than
most of the entries, menu width could be narrowed to just enough for
'normal' lines to fit so that one or two really long entries don't
distort the menu. That's a bit more complicated than I want to deal
with right now. [If implemented, it would be relevant for tty too.]
