jroelofs updated this revision to Diff 246604.
jroelofs added a comment.
Implement review feedback:
- Re-purpose `HeaderFileExtensionsUtils.h` to support headers *and* sources.
- Surround file extension in diagnostic with `''`s.
I have these as two separate patches locally, but I don't know how to represent
that in phabricator, so I've uploaded the diff across both. If this gets
approved, I intend to push them as separate commits.
