I would also like to hide the entire "duplicate" header line, as the
navigation buttons are in the "real" header line, and the file and
title is in the mode-line (and printed in nice big letters in the top
of the info buffer) -- so every bit of information in the header line
is superfluous in general ... except if you want to copy it.
I would then add a command `+' to toggle the visibility of the header
line in case you really need to look at or copy it.
The following patch to info.el does this:
