mdocml: Slightly increase widths calculated from string lengths (mainly

[schwarze@mdocml.bsd.lv]

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.

Issue reported by Jan Stary <hans at stare dot cz>.
