Lucien Kong 2d1ccebae4 status: better advices when splitting a commit (during rebase -i)
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
