Thus, confirmed. Also, it should be an easy hack for a new contributor. Just
process the optional parameter, store the filename somehow, and when printing
diagnostic, use the canonical name if it exists. Also, adjust the #line
directive, so this works even in preprocessed files. I don't think it should
mess up with the original LOCATION_FILE(), since that is used for various other
things.
