addremove: correctly handle intermediate symlinks

This fixes problems mentioned in issue660 comments (unrelated to original
issue) where directory was renamed, and symlink was added instead.
In such situation addremove wasn't able to correctly detect that old files
no longer here, but tried to add symlink (and failed due collision with
old files).

#!/bin/sh

"$TESTDIR/hghave" symlink || exit 80

echo "[extensions]" >> $HGRCPATH
echo "mq=" >> $HGRCPATH

hg init
hg qinit
hg qnew base.patch
echo a > a
echo b > b
hg add a b
hg qrefresh
$TESTDIR/readlink.py a

hg qnew symlink.patch
rm a
ln -s b a
hg qrefresh --git
$TESTDIR/readlink.py a

hg qpop
hg qpush
$TESTDIR/readlink.py a
