bug#13736: 24.3.50; (emacs) `Editing Format Info' typos

[Drew Adams]

In the Emacs doc, menu items and menu names are generally wrapped with
`...' to separate them from the surrounding text.  See (emacs) `Fonts'
for an example.

In node (emacs) `Format Info', this is not the case, but it should be.
