This will be necessary to ensure we maintain reasonable
performance when we add diff-highlighting support.

Still working on VCS integration and I'm not comfortable deploying
this on the main public-inbox.org because of performance/fairness
concerns, yet.

But, perfect is the enemy of good and I figure it's worth
publishing at the moment.  It's also on a Tor mirror:

    http://hjrcffqmbrq6wope.onion/meta/
    http://hjrcffqmbrq6wope.onion/git/

It looks great to me in Netsurf and dillo :>

People with machines powerful enough to run Firefox
(or Tor Browser Bundle) can use "View -> Page Style" to adjust
colors.

Performance considerations:

* diff highlighting alone adds 10-20% overhead to message rendering
  Maybe I can speed it up with some less-readable Perl...

* blob reconstruction is horribly unfair to other clients at the
  moment.  Fixing this is a priority for me.

I haven't hooked up highlight to blob viewing, yet; but that's
coming; too.

Thinking about it more, the blob lookups is so specific to git
that I'm not sure other VCSes can be supported...

The following changes since commit 55db8a2a51c13aec813ac56bbaac1505791fd262:
                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
