That is a reasonable workaround, I guess, for a programmer to override inappropriate behavior that can occur now. I should have separated #1 and #2 not as alternatives, but as two approaches that should both, I think, be taken. Do you think the code as written in help-mode.el is correct? Do you not think that the cond clauses are just wrong? Note that only a couple of the cond clauses have the weird form of putting part of the test for type in the result, and not in the test part. The other clauses have, as one might expect, all of the testing in the condition part, and only the `help-xref-button' call in the result part. (That doesn't prove that the same approach should be taken for all of them. But it does suggest a possible miscoding.) I think it would be good to take a close look at this. And also to document the workaround, letting people know of a _recommended_ way to override the default behavior.
