troff cs problem stumps local experts

[lapoint at BRL.ARPA]

Haven't had a chance to do more than scan your file at this point, but the
use of -ms with the commands therein rings lots of warning bells. In general,
one is well advised to avoid the native troff commands when using the ms
macros -- they screw each other up.

"Typing Documents on the UNIX System: Using the -ms Macros with Troff and
Nroff" by M. E. Lesk, p 5, lists only 4 commands guaranteed to work with
ms (admittedly, the implication is made that others work).

The MS(7) man page states explicitly that "many" troff requests are unsafe,
and then lists 6 which are known to be safe.
