Revert changeset c67920d78248.

It breaks 'hg merge && hg up -c REV' when files exist only in one of the
manifests, making hg throw a traceback like:

#!/bin/sh

hg init test
cd test
echo a > a
hg ci -Ama

cd ..
hg clone test test2
cd test2
echo a >> a
hg ci -mb

cd ../test

echo % expect ssl error
hg serve -p 20059 -d --pid-file=hg.pid
cat hg.pid >> $DAEMON_PIDS
hg --cwd ../test2 push http://localhost:20059/
kill `cat hg.pid`

echo % expect authorization error
echo '[web]' > .hg/hgrc
echo 'push_ssl = false' >> .hg/hgrc
hg serve -p 20059 -d --pid-file=hg.pid
cat hg.pid >> $DAEMON_PIDS

kill `cat hg.pid`

echo 'allow_push = unperson' >> .hg/hgrc
