Allow adding patches to existing merge requests
When a merge request already exists, we could specify an email address that can be emailed to comment on the merge request, including patches that should be applied to the merge request.
Further details
This would be a prerequisite to git send-mail sends multiple emails.
Additionally, the special email could be BCC'ed when working on a feature externally and GitLab could be used to visualize the conversation
Proposal
By including the merge request id in the subject line to the merge request id, parse the email as a comment and a patch to the existing merge request.
