**reconcile.php** __repository_callsign__
Reconcile the state of Phabricator's caches with the actual state
of the repository.
This is an administrative/maintenace operation and not generally
necessary, but if repository history has changed or been rewritten
(for example, if the repository was stored from a backup)
Phabricator may think commits which are no longer present in the
repository still exist.
This will delete all evidence of commits which Phabricator can't
find in the actual repository.
