Probably did. I guess I need to spend more time with :help syn-define.

Cool! Thanks! I had to make a slight modification to what you put up
there:

syn match kconfigPathError '\s*[^"].*$' contained

Otherwise, the obvious space prior to the path matches and the string is
accepted. I want it to fail for anything not quoted. So, the
modification is to allow any whitespace then look for anything not `"'.
But that really helped. I am super grateful!

Thanks again!
Andy
