These changes are important for correctness. Thanks for fixing
them.
It is kind of ugly to have to do file escaping all over the
source. I'd rather see all the os.system() calls go away, in
favor of subprocess.Popen(). You can use the latter without
going through the shell at all, hence no escapes are needed.
If you feel ambitious, this would be a nice fix.
Spaces can happen in depot paths too. That isn't handled
current. All the p4Cmd and p4CmdList calls that work on
depotPaths should avoid going through the shell too.
But at least what you have done already should go in. If you
feel adventurous, addressing these other space-related issues
would be nice too.
