So is the plan to add a completion metadata `eager-display' such that
completion tables can request immediate display? This completion
metadata can then be overridden by the user via
`completion-category-overrides'. The patch would include changes to tmm,
ffap-menu and imenu (obsoleting `imenu-eager-completion-buffer').
