After upgrading to phabricator 524e8a, trying to open a specific, existing Differential revision I get an error
> Unhandled Exception ("RuntimeException")
Undefined variable: commits_for_links
That particular differential revision was created without repository-linking, from a bare diff. The revision has comments and was in the state planned changes.
The diff that it was created with was a combination of three diffs generated with `git diff`. One file path had two diff sections, which the previous version of phabricator we were using was fine with. The previous version must have been c40420.
