Multiple revision undos would also benefit from an automatic summary. FlaggedRevs does this already when rejecting edits, see RejectConfirmationFormUI class.

@Cenarium: good first bug tasks are self-contained, non-controversial issues with a clear approach and should be well-described with pointers to help the new contributor. Given your current short task description I'm removing the good first bug tag.
Please re-add the good first bug tag once the task description has been polished and provides sufficient information for a new contributor. Thanks!
