If I demaximize the frame while the Info buffer is selected and the
empty line is displayed, then the latter remains visible.  But it
disappears after switching to the other buffer, and, with the frame
demaximized, when I switch back to the Info buffer again, it now no
longer reappears.  Moreover, if I now maximize the frame again, with the
same window configuration, the empty line still doesn't reappear.  In
fact, it turns out that it only appears if I maximize the frame before
opening Info the first time; if I then kill the Info buffer with the
frame still maximized and then open Info again, the empty line no longer
appears.

That's also what I assumed.
