[PATCHv4 3/4] t5520-pull: --rebase with rebased upstream and two branches

["Santi Béjar" <santi@agolina.net>]

If you have two branches tracking an upstream that is rebased,
currently you have to do:

git checkout branch1
git pull --rebase remote branch
git checkout branch2
git pull --rebase remote branch

The second rebase works because the first "git pull --rebase" does not
store in the local tracking branch the new value, so the second rebase
detects that it is rebased.

I think one should be able to do the same without the explicit
arguments to "git pull --rebase", but without arguments it stores the
new state of the remote branch so the second "git pull --rebase" does
not work.

Mark this case as test_expect_failure to make people aware of this
behavior.

Changes since v3:
  - Move the "git rebase --abort" to the failing test to not polute the
    next test.

Hi,

I just wanted to make people aware of this behavior and then decide if
this is the correct behavior. Then we can document it, or try to find a better
solution.

Santi
