rsyncability of fsfs f6

The question of keeping a FSFS mirror repository using rsync came up.
For FSFS f4 it's possible to do an rsync of just the rev file + revprop
file + 'current' from post-commit. (Yes, the prior revisions must be a
byte-for-byte match, and min-unpacked-rev must agree as well.
As to rep-cache.db, it is not needed on the mirror.)

In short, for f4 it seems to be a pretty efficient way of sync, although
of course it comes without forward-compatibility guarantees (i.e., it
has the acceptable-to-our-use-case caveat that it might stop working
come 1.8 or 1.9).

Does this property hold for f6 / 1.8?
