 Committing a change to f1 in r1 must break up hardlink f1.i in r2:
 
   $ echo c1c1 >> f1
   $ hg ci -m00
   $ cd ..

 Create a file which exec permissions we will change
   $ cd r3
   $ echo "echo hello world" > f3
   $ hg add f3
   $ hg ci -mf3
   $ cd ..
 
   $ cd r3
   $ hg tip --template '{rev}:{node|short}\n'
   12:d3b77733a28a
   $ echo bla > f1
   $ chmod +x f3
   $ hg ci -m1
   $ cd ..
 
 Create hardlinked copy r4 of r3 (on Linux, we would call 'cp -al'):
 
   $ linkcp r3 r4
 
 'checklink' is produced by hardlinking a symlink, which is undefined whether
 the symlink should be followed or not. It does behave differently on Linux and
 BSD. Just remove it so the test pass on both platforms.
 
   $ rm -f r4/.hg/cache/checklink
 
 r4 has hardlinks in the working dir (not just inside .hg):
