test-hardlinks: add testcase for repo copied with 'cp -al'

This patch adds a case to test-hardlinks.t which demonstrates that
hardlinks in the working directory are broken up (using 'hg update').

Motivation for this patch:

'hg help clone' shows copying repositories *and* the working directory
using 'cp -al', creating hardlinks in the *working directory* too (not
just in the store).

Note that we can't use 'cp -al' since for example MacOS X doesn't
support these options on cp. I'm thus using the same trick as in
test-hardlinks-safety.t for creating hardlinks in the working dir.

Just exercize debugindexdot
Create a short file history including a merge.
  $ hg init t
  $ cd t
  $ echo a > a
  $ hg ci -qAm t1 -d '0 0'
  $ echo a >> a
  $ hg ci -m t2 -d '1 0'
  $ hg up -qC 0
  $ echo b >> a
  $ hg ci -m t3 -d '2 0'
  created new head
  $ HGMERGE=true hg merge -q
  $ hg ci -m merge -d '3 0'

  $ hg debugindexdot .hg/store/data/a.i
  digraph G {
  	-1 -> 0
  	0 -> 1
  	0 -> 2
  	2 -> 3
  	1 -> 3
  }
