[RFC/PATCHv2] git-p4: handle files with shell metacharacters

Updated git-p4 changes incorporating Pete's comments.

 - p4CmdList's stdin argument can now be a list.

 - Getting rid of the string option entirely is very hard; there are
   places where currently git-p4 creates a pipeline.

 - I wonder if verbose should actually be enabled for all the test
   cases?

 - The $ENV{PWD} is needed now because the shell used to set that; now
   that the shell isn't in use git-p4 has to set it.

Pete - I wasn't sure whether you were saying I should rework my patch against next (and you would then rework your series) or something else. That sounds complicated though - let me know!

Thanks! Luke
