I am not an expert in this area by any means.  You are
welcome to submit a patch to modify the current behaviour. 
I don't know if the patch is likely to be accepted.  You can
also bring this issue up on comp.lang.python
(python-list at python.org).  It's probably not appropriate for
python-dev.

Nonetheless, keeping an initial double slash renders this
function useless for its expected purpose.  If this cannot
be fixed outright, could be add a flag (with doc) to provide
the expected behavior (i.e., squish all multiple slash
sequences)?

This document (link below) says "Application developers
should avoid generating pathnames that start with "//".
Implementations are strongly encouraged to avoid using this
special interpretation..."

This is the intent of the code.  The comment says:
    # POSIX allows one or two initial slashes, but treats
three or more
    # as single slash.

Therefore, I'm closing this as Invalid.
