This looks like a good start.  I've commented on the individual patches,
but apart from the patch order and struct commit_info question they're
all minor.

I have a general question, possible more for any administrators of CGit
sites who happen to see this: Should we offer a configuration switch to
disable the blame function?  Blame is a comparatively expensive
operation compared to everything else we do to display a page, so is
there a desire to disable this feature for sites worried about resource
usage?


Finally, some general comments on the output formatting in the browser:

- Should the commit SHA be fixed-width?  I'm comparing the output with
  http://repo.or.cz/git.git/blame_incremental/HEAD:/branch.c which I
  think is a bit easier to read.

- The tooltip looks very confusing since the labels and values aren't
  aligned.  I'd simplify it to show either the author's name and date
  (like GitWeb in the link above) or just the commit message.
