FWIW, I've repaired well over 400 broken Subversion revisions by
hand... and having the FSFS format be so human-readable has been
tremendously beneficial.  Note that the FSFS format isn't entirely
human-readable: the actual deltas are stored as binary.  Despite that
fact, it's still been very useful.
