## concrete design
Make git-annex:version be used by newer git-annex versions than v5,
Make git-annex:difference.log be used by newer git-annex versions than v5,
and by nonstandard configurations.
The file contents will be "timestamp uuid [value, ..]", where value is a
serialized data type that describes divergence from v5 (since v5 and older
don't have the git-annex:version file).
don't have the git-annex:difference.log file).
So, for example, "[Version 6]" could indicate that v6 is being used. Or,
"[ObjectHashLower True, ObjectHashDirectories 1, BranchHashDirectories 1]"
indicate a nonstandard configuration on top of v5 (this might turn out to
be identical to v6; just make the compare equal and no problem).
git-annex merge would check if it's merging in a git-annex:version from
another repo that doesn't match the git-annex:version of the local repo,
git-annex merge would check if it's merging in a git-annex:difference.log from
another repo that doesn't match the git-annex:difference.log of the local repo,
and abort. git-annex sync (and the assistant) would check the same, but
before merging master branches either, to avoid a bad merge there.
The git-annex:version of a local repo could be changed by an upgrade
The git-annex:difference.log of a local repo could be changed by an upgrade
or some sort of transition. When this happens, the new value is written
for the uuid of the local repo. git-annex merge would then refuse to merge
with remote repos until they were also transitioned to the new version.
with remote repos until they were also transitioned.
(There's perhaps some overlap here with the existing
git-annex:transitions.log, however the current transitions involve
