The bug is really minimal: a missing '@'.
But if you use the  emacs-19.26-19.27-diff  
and then re-make the info file (as is suggested),

% cd man
% make info

you get

makeinfo emacs.texi
Making info file `../info/emacs' from `emacs.texi'.
./custom.texi:1582: Unknown info command `yoyodyne.com")'.



Here is the patch  [emacs-19.27 !]:
