Include diffstat in "new MR" emails
Problem to solve
MRs often contain very little description of what they actually change, especially when they are used a lot for small changes and not just massive merges.
The title and description usually explain "why", not "what".
Showing a diffstat in the notification email for new MRs would at least tell the potential reviewers what is being changed.
Proposal
Include the output of git diff --stat (aka the diffstat) in the first email notifying of a new MR.
