Ah, the 28.1 NEWS says: *** New keybinding 'C-h R' prompts
for an Info manual and displays it.  so it's just the
binding that's new, or maybe the completion?

Agreed, though on my system it's more like tens of files so

Info-dir-contents if it was non-nil, though this wouldn't
work before there was an *info* buffer.
