Further investigation suggests that this may be related to a bug in the 
MSYS
console.  When I execute the above command, it hangs permanently; my only
recourse is to kill the process, and its associated tty, with 'kill -9'.
However, remembering a tip I wrote in README.MinGW, if I run

   cat | groff -Tps -mom macros.mom

I can recover the prompt by hitting Ctrl-D, to force EOF on STDIN -- but
*why* is this waiting for STDIN in the first place?

Best regards,
Keith.
