Thanks, everything works well.  Would be nicer to add all available
choices to xref-show-definitions-function (i.e. "at bottom", "minibuffer").

There are still too many differences between them.  The most noteworthy
is that xref--show-defs-minibuffer doesn't show completions by default,
only after TAB TAB.
