Passthrough git aliases

[FlamingTempura]

Great project! I've been searching for something to handle stacked PRs since phabricator's demise. My colleague pointed me to graphite.

I make use of git aliases - e.g git ci for commit, git pr for opening github PR.

The docs specify "gt will pass any unrecognized commands thru to git". However it seems that graphite only passes through known github commands.

Is there any plan to allow aliases to be passed through?
