[StGIT PATCH] Add an --smtp-server commandline option to "stg add"

["Karl Hasselström" <kha@treskal.com>]

The configuration option stgit.smtpserver is useful if you always talk
to the same SMTP server. But I usually set up a temporary ssh tunnel,
so I'd rather have a commandline option.

This patch is sent using the --smtp-server commandline option. Pure
magic!
