> This was a win! Nearly 2x faster `git-annex get` seeking.
Also, limits that look up keys still do, before the keys are looked up
efficiently. Avoiding that would speed up --in etc, probably another
1.5x-2x speedup when such limits are used. What that optimisation needs
is a way to tell if the current limit needs the key or not.
If it does, then match on it after getting the key, otherwise before
getting the key.
Some calls to ifAnnexed, whenAnnexed, lookupKey remain, and the above could
be used to remove them and make it faster. In particular, Command.Sync has
a ifAnnexed.
Also, limits that look up keys still do a key lookup, before the key is

2x too..) Avoiding that would speed up --in etc, probably another 1.5x-2x
