Add xref-find-references to xref-prompt-for-identifier

[MaskRay]

Expected behavior

xref-find-references reads the identifier at point, instead of reading it from the minibuffer.

Actual behavior

xref-find-references prompts for the identifier to look up.

This is because xref-find-references is not in xref-prompt-for-identifier.

Steps to reproduce (recipe)

Call xref-find-references at an identifier.

I didn't know about that, thanks!
So you want xref-find-references to be in xref-prompt-for-identifier by default ?
I think this is a good idea, but helm-xref only displays the results provided by xref. Maybe you should send a patch to an emacs mailing list ? I don't think helm-xref should override xref settings, except the display method.

I send an email to help-gnu-emacs@gnu.org , don't know whether that would create an issue ...

From the manual

When you have all these pieces, bundle them up in a mail message and send it to the developers. Sending it to bug-gnu-emacs@gnu.org (which is the bug/feature list) is recommended, because that list is coupled to a tracking system that makes it easier to locate patches. If your patch is not complete and you think it needs more discussion, you might want to send it to emacs-devel@gnu.org instead. If you revise your patch, send it as a followup to the initial topic.

Thanks! I spelled the wrong mailing list in the first place. It is now reported at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=29619
