Okay, everything makes much more sense in that context.  I certainly
don't want "the perfect" to be the the enemy of "the good", I just
didn't know your current thoughts.  When/if we start committing
fulltexts, we can look at my suggestion then.

John, what's your current thinking on xdelta?  I'd like to replace knits
with *something*, because I think the knit delta format has some
defects.  I'd be happy to do mpdiff, and I'd be curious to see whether
the C patience matcher levels the playing field in terms of speed.  But
I'd also rather xdelta than knit.
