[Python-Dev] Intended behavior of backlash in raw strings

I'm trying to determine if this is intended behavior:
>>> r"\""
'\\"'
>>> r'\''
"\\'"
Normally, the quote would end the string, but it gets escaped by the
preceding '\'. However, the preceding slash is interpreted as 'not a
backslash' because of the raw indicator, so it gets left in verbatim.
Note that it works anywhere:
>>> r"testing \" backslash and quote"
'testing \\" backslash and quote'
It happens that this is the behavior I want, but it seemed just as
likely to be an error. I tested it with python2.5 and 2.6 and got the
same results.
Is this something I can count on? Or is it undefined behavior and I
should really not be doing it?
