Apparently, @mmodell imported some commits from upstream phabricator to a repository hosted on diffussion here: arcanist/stable

Those commits had mentions to phabricator.org tasks, which resulted in actual mentions and closing several unrelated tasks on wikimedia's phabricator.

Tasks were closed when the summary contained strings like "close (task number)" or "fixes (task number).

See for example:

• rARC719eaeecf305 (closed the task)
• rARC61d908b2d163 (changed status from declined to resolved)

This generates unnecesary noise, and links unrelated commits to tasks

There should be a way to "ignore" the summary of any commits on a repository
