Yes.

No, it is a bug in mandoc, not in firefox.

At this point, we still have "font-weight: normal;".
So the column width is (about) 13 normal-weight characters.

But here, we print 13 bold characters.
They don't fit and get wrapped.

Yes, the above is generally no problem width fixed-width fonts.
In mandoc -Tascii and mandoc -Tutf8, it also works fine.
Similar issues might exist in PostScript and PDF, but i'll
treat that as a different story for now.
Thanks for mentioning this,
Ingo
Log Message:
-----------
Slightly increase widths calculated from string lengths (mainly
for .Bl -tag lists and SYNOPSIS .Nm blocks), such that the text
still fits even if it is printed in bold font.
This is an ugly band aid - but implementing font-dependent width
measurements would be a major project and even more difficult
for HTML than for PostScript.
