New feature discussion: git rebase --status

(Got the idea from:
https://git.wiki.kernel.org/index.php/SmallProjectsIdeas#git_rebase_--status)

When in the middle of a rebase, users can be easily confused about
what to do, or where they are in the rebase process.

All the information is available in .git/rebase-merge/, but I believe
it would be helpful to have a command (for example 'git rebase
--status') which would explicitely indicate the state of the process.

For instance, the output could look like:

$ git rebase --status
Rebasing my_last_commit onto base_commit
Already applied 2 patches:
	b170635... my_commit_message
	b170635... my_commit_message
Currently applying b170635... my_commit_message
2 patches left to apply:
	b170635... my_commit_message
	b170635... my_commit_message


Another nice thing could be to improve the output of 'git status' by
saying the number of patches left to apply.
As an example, it could say:
	You are currently rebasing (patch 3/5).

What do you think?
Does the name rebase --status seem appropriate?
Should the output be providing more/less information?
