In cases where numcopies checks prevented the resumed move from dropping
the object from the source repository, it now relies on a log of recent
moves to replicate the behavior of the interrupted command.
Performance: Probably noticable impact, since it has to add to the log,
check the log, and remove from the log. Seems worth it to avoid this
annoying edge case. The log functions are pretty well optimised to avoid
unncessary work.
An performance improvement to make later would be to avoid cleanup doing
anything if it's not written to the log file, and has confirmed that the
log file does not contain the log line.

Those are not installed by git-annex but by the user, and so removal
will never find the default content, and so if the user did install
them, it would display a misleading message.
Seems better, since the user installed them, to let the user remove them
if they want to.
When I put in Haskell98 this spring, I was under the mistaken
apprehension that ghc defaulted to that. But it actually its default
is a third mode, which is closer to Haskell2010 but with some differences.
The manual says "By default, GHC mainly aims to behave (mostly) like a
Haskell 2010 compiler"
Fixed two cases where the Haskell98 do indentation flexability let
wrongly indented code build. That is one of the places where
ghc does not behave like Haskell2010 by default.
The other place that I think I was concerned about, is GHC manual
section 19.1.1.3. Expressions and patterns. But that only seems to
affect code using bottoms, so would only affect pure functions throwing
an error, which I don't think git-annex does in many places as it's
pretty horrid style. And it would only affect rare cases like shown in
that section. If it did happen, it would mean that the error was not
thrown before specifying Haskell98, and then was. Haskell2010 behaves
the same as Haskell98.

The problem was this line:
cleanup = and <$> sequence (map snd v)
That caused all of v to be held onto until the end, when the cleanup action
was run.
I could not seem to find a bang pattern that avoided the leak, so I
resorted to a IORef, rather clunky, but not a performance problem because
it will only be written once per git ls-files, so typically just 1 time.
