From: Luke Shumaker <lukeshu@xxxxxxxxxxx>
It's unclear what the purpose of t7900-subtree.sh's
`subtree_test_create_repo` helper function is. It wraps test-lib.sh's,
`test_create_repo` but follows that up by setting log.date=relative. Why
does it set log.date=relative?
My first guess was that at one point the tests required that, but no
longer do, and that the function is now vestigial. I even wrote a patch
to get rid of it and was moments away from `git send-email`ing it.
However, by chance when looking for something else in the history, I
discovered the true reason, from e7aac44ed2 (contrib/subtree: ignore
log.date configuration, 2015-07-21). It's testing that setting
log.date=relative doesn't break `git subtree`, as at one point in the past
that did break `git subtree`.
So, add a comment about this, to avoid future such confusion.
And while at it, go ahead and (1) touch up the function to avoid a
pointless subshell and (2) update the one test that didn't use it.

v2:
- Also switch the few uses of vanilla test_create_repo over to
subtree_test_create_repo. In v1 this was erroneously included
in a different commit.
