Some implementations of cp can't create hardlinks (replaces 'cp -al' on Linux):

  $ cat > linkcp.py <<EOF

Update back to revision 11 in r4 should break hardlink of file f1:

  $ hg -R r4 up 11
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Test hardlinking outside hg:

  $ mkdir x
  $ echo foo > x/a
