At a minimum this will require documentation for the new command line
option; I would also recomend a NEWS entry.  Oh, and you added a
#include, so you need a Makefile update too.

I noticed while looking for the right place to put the option that we
have an empty "set serial".  Perhaps it should go under that instead.
No strong preference.
