Re: groff 1.19.1 complains when formatting its own man pages

I looked into it some more by using "gdb" and "truss" (it would be
nice if the original diagnostic had been clearer, but I'm not enough
of a groff expert to implement that) and discovered that the problem
is in the following line in the definition of the }S macro in the
Solaris /usr/share/lib/tmac/an:

.if "\\$1"2" .if !"\\$5"" .ds ]F\^

I suspect groff is complaining about the lack of a space between the
]F and the \^.  Such a complaint would normally be correct for groff
input, but here groff is reading from an old-troff macro defined by
the system, so it shouldn't complain.

The same problem occurs in both Solaris 2.5.1 and Solaris 9 as well.
