I'm not sure if the early string conversion would work.  The problem is that the `\` replacement would escape the backreference.  So you end up with problems in the back-reference.  The wrapper ensures that they do not get replaced away as the path separator.

I agree with @tbkka about this being the most concise approach to solving the issue.

@gribozavr2, do you have any other suggestions on how to handle that?
