"Pathname canonicalization now leaves a leading `//' intact, as POSIX.1 
requires."

That's in the release notes for bash-2.01-release.

So it seems this was on purpose. In notes for newer releases there are 
number of allusions to adjustments to // behavior, so it seems that 
maybe this hasn't been a happy feature, but I think its definately a 
feature.

Looking harder, at the BASH FAQ this time, I see:

E10) Why does `cd //' leave $PWD as `//'?

POSIX.2, in its description of `cd', says that *three* or more leading
slashes may be replaced with a single slash when canonicalizing the
current working directory.

This is, I presume, for historical compatibility.  Certain versions of
Unix, and early network file systems, used paths of the form
//hostname/path to access `path' on server `hostname'.

So, there you go.

You can code around it as others have suggested, I guess.
