Actually it's important that we do not use Java's URLDecoder then. Since
we have to run all paths through a decoder routine any '+' would have
to be escaped if we used java.net.URLDecoder. We should provide our
own decode() that' *does not* decode '+'. If of course a user uses '+'
they will get File not found or create files with '+' but that would be
user error because a) they shouldn't be enoding path components b) it's
not defined by the spec and c) they should use the jCIFS provided
decode(). I wonder why Java didn't stop encoding the '+'. I guess if
they decode it they have to encode it too and either way they start to
ruin backwards compatability.
