One day I grew tired of saving stuff into a file and then printing the file,
so I hacked Mail to allow one to "s |cmd".  I took the easy route and ignored
the problem of not being able to "s |cmd arg".  It seems to cover about 90%
of my needs.  The diffs are pretty simple and follow.  You can take them or
leave them!
