At that point, we don't yet know if ID Utils will be used, or GNU 
Global, or something else.

Maybe we should forget this complication and simply ask the user to 
visit the tags file first (it's the etags backend, after all).

That just seemed awkward to me, because the contents of that file aren't 
used at all in this scenario (only its location).

How come that's a factor? 'mkid' scans the subdirectories.

Yup.

Not a bad heuristic. The buffer said "No 'ID' file found" when I was 
dealing with a bug in my code. But that wass an error as well.

I think we can add that non-empty assertion to 
`semantic-symref-parse-tool-output'.
