I've just looked at the 1.5.2 docs and realised that this is
what it *says* it does! So it's right according to the docs,
although it's obviously useless as a pathname manipulating
function.

The question now is, do we change both the specification and the
behaviour, which could break existing code, or leave it be and
add a new function which does the right thing?
