$ vim ...
$ git commit -a -m f
$ git rebase -i
<move the commit I want to upload to the top of the change list>
$ arc diff --update <update ID> --head <sha1 of the commit>
Of course, that doesn't work if the patch relies upon other patches.
However, if I keep the patches in order in git, then arc will upload all of
the parent changes to that Phab revision.

This is part of my issue. The arcanist tool is meant to be used with
Phabricator, especially if you develop in a terminal, but people seem to
actively avoid using it. I personally find it far too easy to push the
wrong changes to a revision.
