Successive slashes are legal (and should be compressed).

But I can see where you are right, if the Netware port doesn't accept the
'/foo' path, then it's wrong (but I thought '/foo' implies local:sys/foo).
So we should special-case this result on Netware.

I'm almost of a mind that since 'machine:vol\path' is the normal syntax, and
we have several platforms which support similar, that we might want to permit
'//machine/vol/path' on Netware as a portable syntax, accepting either <shrug>.
