Also, since we are changing the repr output, would we prefer:

repr output: <test/path path="c:/windows/test.exe">

or:

str output: <test/path path="c:\windows\test.exe">

I thought about this before and I think I prefer the latter (str output). However to make the quoting of repr() work correctly I had to emulate that behaviour in pure Python. Using repr() directly would result in the \\ getting escaped to \\\\.
