Another hidden gem of groff's treasure chest:
It is possible to control the width of \| and \^ on a per-font basis.
If the font definition file of the current font contains entries for
`\|' and `\^', respectively, the specified widths are used instead of
the default values. [Normally, a font definition file contains a
single glyph name starting with a backslash, namely `\-'.]
I've discovered this right now because I had to fix a nasty bug with
\| and \^ for -Thtml and -Tutf8 (which emitted a space instead of
ignoring them). Users of the CVS, please upgrade.
