Yes, and a documented one:  an r-string cannot end with an odd number of
backslashes.  Note that your first expression ('\\') did create a string
with a single backslash, although the repr of that string may have fooled
you into thinking you got two backslashes.

>>> print '\\'

Nope:  it's not a bug, and won't change.
