Re: git-blame.el: what is format-spec?

Then there should be (require 'format-spec) in git-blame.el, right? Due
to:

Of course. I must have missed that since I already had it loaded.

Now, I've evaluated (require 'format-spec) in my Emacs 22 (yes, 22, not
23), and now git-blame almost works there. The problem I see is that it
doesn't output anything in the echo area. It color-codes the buffer, it
does show correct pop-up when mouse is over a region, but it doesn't
print anything in the echo area when I move cursor through the regions.
Any idea how to debug/fix this?

Well, it appears I removed the output to the echo area. I didn't think
it worked very well, and the new output format mostly replaces it by
showing the hash.

There are also technical reasons for removing it (it couldn't be
implemented very cleanly).

I didn't know you deliberately removed it, -- I thought it's some
Emacs22 - related problem. I have no problem then, except that I don't
know how to get the hash into my kill-ring or X selection.

While we are at it, why is git-blame-identify interactive and how is it
useful?

It would of course be possible to restore the old way, but I think it
would be good to ask ourselves what we really would like to see? Some
ideas:

* A keybinding to show the commit introducing the current line,
  including diff and all.

* A keybinding to show the commit message in the echo areia.

For me, these 2 would be more than enough, I think.
