Status: RESOLVED FIXED

(Conduit :: moz-phab, enhancement)

Description

[:glob ✱]

add support for git to moz-phab

* crib from [phlay](https://github.com/mystor/phlay/blob/master/phlay)
  * maybe use `git stash` to avoid [fake_git](https://github.com/mystor/phlay/blob/master/phlay#L179)

Note that `git stash` changes timestamps, so this could affect incremental builds in maybe undesired ways.
