right.. I had run in to this in the past when using the comments
instruction for multi-line figure captions. (so the () got split between
lines) slowly it comes back

so it doesn't explain Rich's problem, but he already did..

I can't find a bug report for it or any comment in the code, but ISTR
trying something like that when I ran into it the first time & added
that hint to the man page. shrug. if anyone is interested it's done with
show_text() in ps/ps.map/gprims.c.
