Looks good. And the code volume reduction is significant.

Could you expand this comment a bit? It's not enough of a clue for me.

Very nice parameter rename here, now that we have Branch objects (and
use a crappy language with no type system).

You can remove the parentheses now; they were only needed because they
used to enclose a complicated expression. Besides, shouldn't it be
[branch:]{base} instead of base? So something like

  rev = [<branch>:]<patch> | [<branch>:]{base} | <tree-ish>

Unrelated to this patch: I realized last week that it's silly for stg
files to not accept a patch range.

Ah, so this is the backwards compatibility thing -- we used to pass
the empty string when we meant HEAD.

The corresponding TODO comment now would be that pick should be able
to pick patches from the past, from the stack log.
