windows: avoid deleting non-empty reparse points
If a hg repository including working directory is a reparse point (directory
symlinked or a junction point), then using os.removedirs will remove the
reparse point erroneously. This is fixed by only removing directories if they
are empty.
#!/bin/sh
"$TESTDIR/hghave" symlink || exit 80

echo "mq=" >> $HGRCPATH
