Among other things fixed a while ago,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=256226 reports that
groff uses the 'trap' builtin with numeric signal names rather than
named signal names. POSIX only supports named signal names and '0'; the
other numeric signals are XSI extensions. There seems no reason not to
use the portable forms in groff.
Here's an updated patch.
