Developers of the world, rejoice! :-)
Junio, Pranit (and whoever is paying attention to the conversation
that was being held about --tips), here's a draft of what I meant when
I was talking about the option of "aggregating" blame output. I'm not
considering _all_ cases yet, just would like for people to give it a
quick test and tell me if they think it's worth "polishing" it for
inclusion into mainline git.
The output would look like this:
$ ./git blame -L 1,19 -t --aggregate builtin/blame.c
Blaming lines: 0% (19/2974), done.

It can be seen that options like -t still work in aggregation.
In relation to the previous conversation about "tips", I think a
better name could be "hints" and it could be added on top of the
aggregation.
