Detect half-baked core taps that show up on a fairly regular basis (e.g. #11465). The logic is simple enough: Since an improper tap wouldn't have a complete Git config, and is always somewhere below `HOMEBREW_REPOSITORY`, any Git operation would look at the Brew repo instead. We simply need to test for any of: 1. Empty tap origin 2. Empty tap HEAD 3. Tap HEAD == Brew HEAD

This directory contains all the code run by the official brew command in Homebrew and all formulae (package descriptions) in taps (repositories containing formulae) in Taps subdirectories.
