It'd be good if the texinfo manual had entries for vindex and friends in
the "Command and Variable Index".
I tried Emacs info-lookup-symbol on @vindex, hoping it would go to a
relevant node, but that func needs an entry in the "Command and Variable
Index" for where. Would it be as easy as below (untested!)?
