[StGIT PATCH] Test "stg rebase" after "stg commit"

["Karl Hasselström" <kha@treskal.com>]

Two new tests for "stg rebase":

  1. Try to rebase to a commit that is ahead of HEAD. This should
     work, and does.

  2. Try to commit a patch, and then rebase. This doesn't work,
     because "stg rebase" aborts if orig-base != base, and "stg
     commit" doesn't update orig-base. (It does work if "stg rebase"
     is given the --force flag.)

(2) shows a bug in "stg rebase"'s safety logic. I'm not sure how to
fix it, because I don't know how it's supposed to work in the first
place. (An obvious fix would be to update it whenever the base
changes, but that'll take some work, and I'm not convinced it can't be
done with les work. Yes, I'm lazy.) Yann, could you explain?
