They don't fit and get wrapped. > In lynx it displays fine. 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.
