Prepends a directory to PATH. Is the formula struggling to find the pkgconfig file? Point it to it. This is done automatically for keg-only formulae.

Prepending a system path such as /usr/bin is a no-op so that requirements don't accidentally override superenv shims or formulae's bin directories.

ENV.prepend_path "PATH", which("emacs").dirname
