[PATCH 0/3] send-email: --smtp-domain improvements

The first patch keeps send-email from using a bogus FQDN for my laptop.
Oddly enough, my MTA doesn't mind "localhost.localdomain" but complains
about "My-Computer".

The second adds documentation for --smtp-domain to the git-send-email man
page.  The only documentation for it was in the code and the usage message.

The last is just an enhancement, but I was honestly surprised that
--smtp-domain didn't have a configuration.

Brian Gernhardt (3):
  send-email: Don't use FQDNs without a '.'
  Document send-email --smtp-domain
  send-email: Add sendemail.smtpdomain
