Hmmm .... why didn't we just give "svnadmin create" new flags to control
these features? Editing fsfs.conf every time one creates a new
repository would tend to become a bit tedious.

There's no UI in svnadmin to set the shard size, either.  (Editing
fsfs.conf while HEAD == 0 happens to work with the current
