I see a lot of rerolls on the credential helper front, but is there
anybody working on hooking send-email to the credential framework?

That would work (with my PATCHv6 of the netrc credential helper) as
follows:

1) just host

host=H

maps to

machine H login Y password Z

2) host + protocol smtp

host=H
protocol=smtp

maps to any of:

machine H port smtp login Y password Z
machine H protocol smtp login Y password Z

3) host:port + protocol smtp

host=H:25
protocol=smtp

maps to any of:

machine H port 25 protocol smtp login Y password Z
machine H:25 port smtp login Y password Z
machine H:25 protocol smtp login Y password Z

That's my understanding of what we discussed with Peff and Junio about
token mapping.  Note we don't split the input host, but instead say "if
token 'port' is numeric, append it to the host token" on the netrc side.

Does that sound reasonable?  If yes, I can add it to the testing
Makefile for the netrc credential helper, to make sure it's clearly
stated and tested.
