(2) `x-list-fonts' returns nil when passed such a font (i.e. with fontset-auto8). > From: Drew Adams Sent: Friday, November 28, 2008 1:38 PM > This bug seems still not to be fixed, and I cannot even find > it listed in the bugs database: > http://emacsbugs.donarmstrong.com/cgi-bin/pkgreport.cgi?pkg=emacs. > > What is that status of this bug?
