Add new informative help messages at the output of 'git status' when
the user is splitting a commit. The code figures this state by
comparing the contents of the following files in the .git/ directory:
- HEAD
- ORIG_HEAD
- rebase-merge/amend
- rebase-merge/orig-head

The second test added by this patch fails because the case in which
the user amend the last commit through rebase -i is not taken care of.
We infer that the user would directly run "git commit --amend" instead
of amending it with a rebase -i.
