Yeah, I just looked what filelogs were the largest.

Right, its original manifest size was somewhere in the 800M size. BTW,
on Python's repository, some earlier version did better than Benoit's
latest.

I prefer -revlog. Making it an extension that adds a command called
shrink (without args, manifest, with arg, filelog) might be even
better (although it should probably be in contrib, not hgext).
