It says “Type Space to see more” or “Type Space to return to Info” if
on the last page. This message comes from ‘Info-summary’ which
contains a rudimentary modal scrolling event loop; pressing any key
other than space un-reads that key and hides the help buffer.

However, what is the reason for that event loop? Wouldn’t it be better
to just display and activate the help buffer, and arrange for <SPC> to
scroll it (which ‘help-mode-map’ already does) and additionally allow
scrolling in more familiar ways, such as by arrow keys (which also
automatically work in a non-modal ‘help-mode’ buffer)?
