It doesn't look like VFS/file.php's _getNativePath function has changed between
version 1.44 and the current version (1.50).  The attached patch was written for
v1.44, and was a working implimentation of non-tilde relative paths.  It
doesn't seem to work with 1.50.  I'm not sure why.

The patch appears at the end of this message.
