In "files-backend.c::files_fsck_refs_name", we validate the refname format by using "check_refname_format" to check the basename of the iterator with "REFNAME_ALLOW_ONELEVEL" flag. However, this is a bad implementation. Although we doesn't allow a single "@" in ".git" directory, we do allow "refs/heads/@". So, we will report an error wrongly when there is a "refs/heads/@" ref by using one level refname "@". Because we just check one level refname, we either cannot check the other parts of the full refname. And we will ignore the following errors: "refs/heads/ new-feature/test" "refs/heads/~new-feature/test" In order to fix the above problem, enhance "files_fsck_refs_name" to use the full name for "check_refname_format". Then, replace the tests which are related to "@" and add tests to exercise the above situations using for loop to avoid repetition.
