This happens because font-lock-mode gets turned off in Info buffers. Type "M-x font-lock-mode RET", and all the niceties are back. (You could guess that this is the problem if you'd go to the un-decorated text and type "M-x describe-text-properties RET" there.) The reason seems to be the changes in revision 111794: their result is that, after Info mode is turned on and turns on font-lock, font-lock is turned off again by something called global-font-lock-mode-check-buffers. And to make things _really_ interesting, if you run this under Edebug, the problem disappears... Since the voodoo of easy-mmode is beyond me, I'll let others fix this.
