epriestley 85c953ebe4 Fix a PHP 8.1 repository marker issue in Mercurial ... Summary: Ref T13588. "arc-ls-markers" emits a "branch-state" marker so callers can identify which branch is active in the working copy. This marker doesn't have an associated commit, so trying to generate a display name fails under stricter PHP 8.1 rules when we try to `substr(null, ...)`. Don't attempt to generate a display name for markers with no commit hash. Test Plan: - Ran `arc branches` under PHP 8.1 in a Mercurial repository. - Before: fatal. - After: sensible output.
