This means that to use a mailer command including a colon, one would
write something like

	MAILER='vim -d con$(printf \072)20/30/600/150'

The more obvious “MAILER='vim -d con\:20/30/600/150'” doesn't work ---
it splits as (1) con\, (2) 20/30/600/150.

I can't see an easier way to cleanly support multiple alternative
mailers. I am very happy to have $MAILER working at all, so for what
it's worth, I like the patch.
