I started to look at this, but the basic problem is that we don't
understand X:\ as an absolute path at all - we canonicalise it to X:,
which means something else entirely.

This particular manifestation of the problem is in
libsvn_wc/lock.c:svn_wc_adm_open_anchor(), where we open the parent of
the target (if one exists) and the target itself. In this case, the
parent of "X:" is "", so we try to lock "X:" (which succeeds) and then ""
(which is the same thing, and so fails).

While there's some work to do in libsvn_wc to handle this case, we
need to educate our path routines that X:\ is an absolute path first,
and that seems non-trivial.
