There was a prior report about this but I can't find it; maybe it
didn't go through the web contact form. Anyway, status_hilite
threshold numeric values wouldn't accept a minus sign before the
digits, preventing negative AC values from being tracked.
From Bart...
When we are creating the console font for testing character widths,
we were not specifying width. Because of this, the created font's
average width might be larger then what we expect and we might
falsely detect that the font was inappropriate for playing Nethack.
Fix provides the width that we are expecting when creating the font.
