No, Vincent. I did not launch test suite before, because I was busy.

I'm running selftest now. And I can say that this patch has at least 1 bug.
I have many tests failed with following message:

ERROR: blackbox.test_status.CheckoutStatus.test_branch_status
    attribute 'st_size' of '_walkdirs_win32._Win32Stat' objects is not writable

ATM I have result:

[809/14144 in 7m18s, 165 err, 13 fail, 2 missing] blackbox.test_non_ascii.TestNonAscii.test_pull(cp1251)

So it seems I need to wait hour or so until test suite finished.
