This has not been needed since stack <1.4.0, and even the i386ancent
build uses stack 2.1.1.
Stack 2.7.5 seems to have forgotten about this old config and warns
about it, so this avoids that warning.
The libtinfo-dev was added to the docs at the same time, I assume it is
also not necessary.
(And v9 later on to v10.)
When v9/v10 were added, making v8 automatically upgrade was deferred
"for a few months" to prevent interoperability problems if users also
have an old version of git-annex. Of course that could still be the
case, but there has been a good amount of time and this can't be put off
forever.
Allow setting annex.autoupgraderepository to false to avoid this upgrade.
Previously, that only prevented upgrades from no longer supported git-annex
versions, but v8 is still supported, and users may want to keep on v8 to
interoperate with an old git-annex version.

I would like for a new repo version to enable appends, but to do so
safely would need a v11 followed by a 1 year delay followed by a v12
that does it. Since a similar v9 and v10 transition is currently
happening, and is less than 6 months along in most repos, it does not
feel wise to stack up another year-long transition behind that. What if
I need to hurry up a new repo version for some other change?
Added todo so I remember to make this change at some time when a v11
and probably v12 repo version do make sense.

An append that is interrupted and writes part of a line is now dealt
with by subsequent reads and appends. This also handles a read that
happens at the same time as an append to the file.
Old versions of git-annex will still see a partially written line,
and could get confused. Since appends are currently done for url logs
and location logs, the confusion is limited to a substring of the actual
url or UUID of the remote being read. This will not affect writes, since
the journal file is locked when reading in preparation for writing.
However, the bad data can be output by git-annex and used by other
things, or could cause surprising behavior by git-annex. Including eg,
downloading the content of the wrong url.
So, something needs to be done to prevent old versions of git-annex from
running in a repository where this appending is being done..
