Re: git-p4import.py robustness changes

git-p4import.py should work fine on Windows, too - the binary mode on  
the pipe should be all handled by "subprocess", and git-p4's  
data.replace("\r\n", "\n") is not necessary if you use "LineEnd:  
unix" or "share" in the Perforce client specification.

The problem is that you cannot set the LineEnd when using the 'p4 
print' command, since it doesn't use the client spec; so Perforce the 
uses the platform default when printing the file.

git-p4 seems to use "git fast-import". I guess the big performance
improvement there is removing the ls-files operation? So we're 
talking about a 0-10% speedup, right? Plus some fork()/exec()
overhead.

With git-p4 the performance bottleneck is from what we can see the 
Perforce server, on non-Windows machines.
