Because the original breakage was already in 1.9, not a regression
between 1.9 and master, as the matter of principle our default is to
defer until 2.0 final to avoid risking unintended additional
breakages elsewhere. But this fix is an obviously correct and
trivial single liner that were eyeballed by more than one person,
and that affects only three calls to os.system(), and its
correctness can be seen even without knowing p4 at all by somebody
like me ;-)
So let's queue it for 2.0.
Thanks.
