bug#12105: 24.1; `help-make-xrefs' should not create an xref to the current thingy

[Drew Adams]

Please exclude the current thingy that is being described from
cross-reference creation.  E.g., if I do `C-h f foo' and the doc for
`foo' happens to mention `foo' itself (using the `...' syntax), that
mention should not be turned into a cross reference (which just goes to
the same *Help* output).
 
This might mean adding an argument to `help-make-xrefs' to provide that
thingy.  And that might also mean adding the same arg to
`help-mode-finish'.  An alternative, I suppose, is to use a global
variable for the thingy being documented.

No, I think consistency is better than avoiding the user hitting a
pretty useless link.  Closing.
