This seems a bit awkward...what if the file is included on the command line with -include? (Some of our tests do this.)

I guess it works. I was just expecting something like a last-path-component match, using, say, a search over fileinfo_begin()/_end() in SourceManager.

This should probably be asserted or checked; it doesn't make sense to specify another file without a line number.

I'll look into the 79/80 issue too. Thanks for doing this!
