[StGit PATCH v2 6/6] stg mail: don't parse To/Cc/Bcc in --git mode

[Alex Chiang <achiang@hp.com>]

When using stg mail in --git mode, do not parse command-line To/Cc/Bcc
addresses.

Instead, we pass them directly to git send-email.

This allows us to leverage git send-email's support for email aliases.
