In a v6 repository on a filesystem not supporting symlinks,
it makes sense for commands like
git annex add and
git annex import
to add the files unlocked, since locked files are not usable there.
After implementing that, I also added an
annex.addunlocked config setting,
so that the same behavior can be configured in other repositories.
Rest of the day was spent fixing up the test suite's v6 repository tests to work on FAT and Windows.
