Added annex.skipunknown git config, that can be set to false to change the behavior of commands like `git annex get foo*`, to not skip over files/dirs that are not checked into git and are explicitly listed in the command line. Significant complexity was needed to handle git-annex add, which uses some git ls-files calls, but needs to not use --error-unmatch because of course the files are not known to git. annex.skipunknown is planned to change to default to false in a git-annex release in early 2022. There's a todo for that.
