The only price paid is one additional MVar read per write to the journal.
Presumably writing a journal file dominiates over a MVar read time by
several orders of magnitude.
--batch does not get the speedup because then it needs to notice when
another process has made a change. Also made the assistant and other damon
modes bypass the optimisation, which would not help them anyway.
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

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.
