epriestley 20a5c9b261 Use "closed", not "committed", in Differential
Summary: "Committed" is SVN-specific language, and confusing in Git and Mercurial. Use neutral language instead.

Test Plan: Inspection.

**undo_commits.php** --repository __callsign__ < __commits__
Reopen code reviews accidentally closed by a bad push. If someone
pushes a bunch of commits to a tracked branch that they shouldn't
have, you can pipe in all the commit hashes to this script to
"undo" the damage in Differential after you revert the commits.
To use this script:
1. Identify the commits you want to undo the effects of.
2. Put all their identifiers (commit hashes in git/hg, revision
numbers in svn) into a file, one per line.
3. Pipe that file into this script with relevant arguments.
4. Revisions marked "closed" by those commits will be
restored to their previous state.
