hmm, we'll have to revert part of https://chromium-review.googlesource.com/612822 and update/rework the code to handle this.  if we want to keep the -g option, we'll need to dynamically differentiate between browser & non-browser repos.  but then we wouldn't be able to easily differentiate patches for repos that the two projects share (like chromite itself).  so i think the only sane option would be to add a new option for users to explicitly say "apply this patch to the browser".
