Phabricator keeps the summary field of a revision independent of the commit message (beyond the initial upload). You can use `arc diff --verbatim` to force the summary to be re-copied from the commit message. However, running that will also update the Reviewers and Subscribers fields with their values in the commit message, which would probably drop a lot of subscribers in this case, so I wouldn't recommend it. You can always Edit Revision and update the summary manually if you really want.
