 Create hardlinked copy r4 of r3 (on Linux, we would call 'cp -al'):

 Test that we don't lose the setgid bit when we call chmod.
 Not all systems support setgid directories (e.g. HFS+), so
 just check that directories have the same mode.
 
   $ cd ..
   $ hg init setgid
   $ cd setgid
   $ chmod g+rwx .hg/store
   $ chmod g+s .hg/store 2> /dev/null
   $ mkdir dir
   $ touch dir/file
   $ hg ci -qAm 'add dir/file'
   $ storemode=`python ../mode.py .hg/store`
   $ dirmode=`python ../mode.py .hg/store/data/dir`
   $ if [ "$storemode" != "$dirmode" ]; then
   >  echo "$storemode != $dirmode"
   $ fi
