For performance reasons, we prefer detecting Homebrew prefix internally instead of the more idiomatic form `brew --repository`. We attempt looking up $HOMEBREW_REPOSITORY first (in case `brew shellenv` has been sourced-in earlier). Else, we look it up by resolving absolute path of $HOMEBREW_REPOSITORY. This should work for most standard (and officially documented) Homebrew installations.
