With the mom macros, there's no need to define a macro because of
the '\,' '\/' problem.  The following works in .char definitions:

  .char ( (\*[FU1]\fP
  .char ) \fR\*[FU1])\fP

'FU' stands for Forward Units, and is used, along with 'BU' (Back
Units), for kerning on-the-fly between any pair of characters.
1 Unit=1/36m by default, but can be changed to any fraction you
like.  Thus, it's suitable for making the "italic correction" in
definitions such as the one above.
