Fix tests under git-2.2

[dottedmag]

I have noticed that one of the tests failed under git-2.2

Could you try to make this dependent on version? I.e. with legacy Git, test for it, with 2.2 you don't?

It's been deprecated since 2008, maybe it's easier to just drop it? git/git@1dd1239

+1 on accepting this PR as-is.

I'm on git 2.4.5, and just got hit by this while trying to install and test the feature/foreach branch.

vcsh (rightly) doesn't directly depend on the actual presence or absence of this directory, only on git's external behavior. The whole t/100-init.t suite only has meaning as a collective because each test is fingerprinting the implementation details of git's repo structure. Moreover, I can't imagine a case where vcsh init causes an (old, < v2.2) version of git to pass this suite except for ok -d 'branches';.

Thanks :)
