I do not really understand how info-lookup does its job but 'read' still
matches if I use

    (info-lookup-maybe-add-help
     :mode 'f90-mode
     :parse-rule "[A-Za-z0-9_]+"
     :regexp "[A-Z0-9_]+"
     :doc-spec '(("(gfortran)Keyword Index")))

instead.  Perhaps I do not understand what you have in mind.
