Hi Bert,

s/does only create/only creates/ ?
Anyway, as a prepatory patch, I don't think that it's necessary. Maybe it's just me but I assume that most tools create at most one directory deep. Even mkdir won't created nested dirs unless you pass `-p`. I dunno.

For test case you write, please use the following pattern:
git rev-list master..side >list && test_line_count = $(ls patches | wc -l) list
The first benefit is that we get to take advantage of the test_line_count function that's already written for us. The second is that when we write tests, we shouldn't put Git commands in the upstream of a pipe because if they fail, their return codes will be lost and we won't be able to fail the test properly.

As above, I wouldn't really call this a bug in Git. I think we should leave this test case off until the next patch.
