After updating to HEAD moments ago, we are getting the following error when pulling from a git repo:
$ git pull phabricator-ssh-exec: Invalid command. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
It seems to be a regression in rP368f3591142ed923bcf2a8bf1a48b746794f2f02: an undefined $workflow_names variable is referenced.
