I looked at using "emit_porcelain()" directly, but that format doesn't 
seem to actually be usable for incremental blame.

For example: the porcelain depends on things like the MORE_THAN_ONE_PATH 
flag having been computed, which simply isn't known incrementally.

Also, for the incremental blame, it makes no sense to actually print out 
the actual blame buffer: anybody who uses the incremental blame thing 
really needs to get the original buffer separately set up anyway.

So one one hand, I agree: the output really should probably share a lot of 
the ideas with --porcelain. At the same time, the porcelain output as it 
is now is actually very non-sensible for the incremental case.

(The "METAINFO_SHOWN" kind of logic works fine for --incremental, though. 
It's only the MORE_THAN_ONE_PATH things that don't really make sense until 
the end, since they are part of the discovery logic rather than part of 
the actual print-out logic. I guess it _works_, but still).

I think the people who will care are the people who actually write some 
nice gui around it..
