I can see the logic of changing help-xref-symbol-regexp: Emacs shouldn't
underline inappropriate links.  However, if the user still wants to follow a
keyword thats not underlined, that should be his choice.

Clearly with `locate' the link leads nowhere but in other cases, the value of
a variable e.g features, say, where all explicit/underlined links have been
removed, some keywords may be of interest.  Emacs generally gives you enough
rope to hang yourself and I like it that way.

Yes I could but its not quite as convenient.

Yes.  I'm sure `you're doing it for my own good'.
