Revert "Add new @ shortcut for HEAD"
This reverts commit cdfd94837b27c220f70f032b596ea993d195488f, as it does not just apply to "@" (and forms with modifiers like @{u} applied to it), but also affects e.g. "refs/heads/@/foo", which it shouldn't. The basic idea of giving a short-hand might be good, and the topic can be retried later, but let's revert to avoid affecting existing use cases for now for the upcoming release.
