I copied it from the other filesystem checks. hghave.py seems not that strict
about handling of OSError.

I've pushed that one. Thanks.



On some platforms, cwd can't be removed. In which case, util.unlinkpath()
continues with no error since the failure of directory removal isn't critical.
So it doesn't make sense to run the test added by 90a6c18a7c1d on those
platforms. OTOH, we need to run the test in test-rebase-scenario-global.t
since the repository is referenced after that.

Maybe we should check the errno here too? (as a followup)
