Include patch in Merge request notification
Problem to solve
Some developers would like the current proposed patch in a merge request to be included in the notificaiton e-mail.
Further details
Samba is an old, e-mail based project that traditionally manages patches on a public mailing list with patches attached (preference is one patch file for the full change set).
Samba is starting to use GitLab, and some merge requests have been successfully discussed and merged. So far so good!
However a number of developers use text-based mail clients such as mutt, and feel quite strongly that if notified of a proposed change, the change itself should be attached to the mail, rather than via the included link back to GitLab.
Proposal
Include the patch, as obtained from MR_URL.patch as a MIME attachement in the notification mail.
What does success look like, and how can we measure that?
A UI option in the nofication settings with an option to include patches, and a maximum size patch to include.
