Subject: emacs-25 mishandles info code text on Fedora 23
Date: Fri, 18 Dec 2015 10:25:25 -0800

[Message part 1 (text/plain, inline)]

When I use emacs-25 to view the Elisp manual on Fedora 23 x86-64, Emacs 
mishandles the font for code: code is displayed in a considerably 
smaller font, making the manual harder to read and looking a bit like a 
ransom note. A sample is attached. I am using 'emacs -Q' to read the 
info file. If I view the same (i.e., the emacs-25) info file with Emacs 
24.5 as bundled with Fedora, the display looks fine, with the same 
fixed-width font used for all text.
