Reapply 231888 "Fixes for python 2.7.5 support." with fixes.

Tested to work now with the repro case of bug 313552.

"/c" was interpreted by cygwin's bash as a path and was replaced with c:/. :(
Using //c seems to be passed through properly.
There is probably other escaping problem but this should be good enough at
this stage.

Ouch!

Is there a setopt we can run to disable this instead of the double backslach
hack?

I don't speak bash at all.

cygwin is not even related in this CL. Sorry.

Looks like there's no obvious way to turn it off:

That's unfortunate.

LGTM

Thanks, I added this reference in the CL description so it can be looked up if
someone wants to fix this in a few years.
