Re: [PATCH 6/6] gitweb: use blame --porcelain

Side note.

This change does not give any more information (other than the
link to the corresponding line in the original version) than the
current gitweb in "next", but "blame --porcelain" returns richer
information than it used to be available, most notably the
summary line.  It might be interesting to enhance the title pop-up
mechanism to show them on mouse-over, but I was too lazy ;-).

I've considered making the commit-8 link to link not to the
commit page for the originating commit but to the corresponding
line in the blame page for it, but opted to take over the line
number link, which was serving far less useful purpose.  Your
keyboard has PgUp and PgDn to let you navigate within the same
blame output.

As I noted in the log message for [3/6], I suspect that the
curent implementation to show the original line number is
unnecessarily inefficient.  Improvement is much encouraged.
Again, I am too lazy to look into it right now.
