Heh... amazing what sendmail -q digs up. Turns out that this was
actually fixed the same day I filed the PR, so I thought maybe I'd filed
it confidential by accident. However the cvs notes for the fix indicate
that the -p option can't be called without other flags, when the actual
problem is that amd chokes on the null flag argument if no flags are
specified. Here is a slightly cleaner fix.
