Commits: rARCc39ab20eb371: Correct a PHP8 compatibility issue when running "arc diff" with no active branch

Summary

Ref T13588. See PHI2228. When there is no active branch name (for example, because you are in Git on a detached HEAD), this section currently fails under PHP8 when we try to strlen(null).

Test Plan

Under PHP 8.1: ran git checkout <hash of head>, then arc diff to generate this revision.
