Let's say I forgot to reference a task or made a mistake in my commit comments in a check-in to an external (non-phapbricator-hosted) repository. Diffusion has already pulled in the bad commit comments. Later, I update my commit comments in the repository (i.e. my SVN pre-revprop-change hook returns 1, so I am allowed to modify comments at a later time).

Is there a way to force Diffusion to "rescan/reload" a single revision or the entire repository to pull in the modified commit comment(s)?

If this were a Phabricator Hosted repository would this happen automatically?
