Significant startup speed increase by avoiding repeatedly checking if some
remote git-annex branch refs need to be merged when it is not newer.
One way this could happen is when there are 2 remotes that are themselves
connected. The git-annex branch on the first remote gets updated. Then the
second remote pulls from the first, and merges in its git-annex branch.
Then the local repo pulls from the second remote, and merges its git-annex
branch. At this point, a pull from the first remote will get a git-annex
branch that is not newer, but is not on the merged refs list.
In my big repo, git-annex startup time dropped from 4 seconds to 0.1 seconds.
There were 5 to 10 such remote refs out of 18 remotes.

Eliminated some dead code. In other cases, exported a currently unused
function, since it was a logical part of the API.
Of course this improves the API documentation. It may also sometimes
let ghc optimize code better, since it can know a function is internal
to a module.
364 modules still to go, according to
git grep -E 'module [A-Za-z.]+ where'
This is certianly a cabal bug for not passing the build options in the
cabal file when building Setup.hs.
And, why oh why did ghc enable this warning by default? So unhappy with
this choice.
I forgot I had <$$> hidden away in Utility.Applicative.
It allows doing the same kind of currying as does >=*>
and I found using it made the code more readable for me.

Instead of populating the second-level Bloom filter with every key
referenced in every Git reference, consider only those which differ
from what's referenced in the index.
Incidentaly, unlike with its old behavior, staged
modifications/deletion/... will now be detected by 'unused'.
