Not sure if you care about this, but this script fails when you are in detached head state:

$ git branchls
fatal: ambiguous argument '(detached from rlr/l10n-metrics-889928)': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
