From c37b65ee106352c00ab1615b2bac0a5b9a720137 Mon Sep 17 00:00:00 2001

Subject: Clean up some markup cruft.  A number of the macros that take no
 parameters (like \UNIX) are commonly entered using an empty group to separate
 the markup from a following inter-word space; this is not needed when the
 next character is punctuation, or the markup is the last thing in the
 enclosing group.  These cases were marked inconsistently; the empty group is
 now *only* used when needed.
