Make Find References foo also show refs for foo-setter

[cgay]

If I ask for the references to a slot getter, most of the time I want to know all the ways that slot is used, whether as getter or setter.

Is there any reason why it would be undesirable to show xrefs for foo-setter automatically when xrefs for foo are requested?

NOTE: I think that if someone explicitly asks for xrefs to foo-setter we do not want to automatically show xrefs to foo, because getter use can easily outnumber setter use by a lot and make setter uses harder to see. That's bad if you're looking for those explicitly.

Also it's generally not possible to just M-. the setter because the full name isn't used; you'd have to add "-setter" and then M-. it and then remember to undo the typing. Ick.

Maybe if the cursor | is in x.some-g|etter := or some-g|etter(x) := we can apply DWIM.
