Attoparsec parser for diff-tree.
Changed fromRef back to producing a String, to avoid needing to convert
every use of it. However, this does mean I'm going to miss some
opportunities where fromRef is used and the result converted back to a
ByteString. Would be worth revisiting that at some point maybe.
After a user completely ignored the display of the exception probably
because it didn't make sense..
This does make it a little bit slower since it checks adb is in path each
time before running it. Also, it might display a lot of warnings about it
not being installed.

Improve git-annex's ability to find the path to its program, especially
when it needs to run itself in another repo to upgrade it.
Some parts of the code used readProgramFile, probably because I forgot that
programPath exists.
I noticed this when a git-annex auto-upgrade failed because it was running
git-annex upgrade --autoonly, but the code to run git-annex used
readProgramFile, which happened to point to an older build of git-annex.
This was originally added so that unannex could prevent the hook from
running while files were in a state that the hook would interpret as
old-style unlocked and so would lock.
Now that's gone, so the only thing the hook was preventing was two
pre-commit processes running simulantaneously. But such concurrency
is normal in git-annex and should not be a problem.
Does mean that .git/hooks/pre-commit-annex might run more concurrently,
that seems the only risk of it causing any problems.
