Revert "Omit edition numbers and dates in manuals"

This reverts commit 2f42832895942fdeaa0c500511aa19860fa806cd.
Editions of Emacs manuals must be coordinated with the FSF
publishing staff, as they appear on the printed books.

+@c The edition number appears in more than one place in this file
+@c I don't really know what it means...
+@c For example, it has said "Sixteenth" since sometime in the Emacs 22
+@c series, all through 23, and into 24.  So it is not very useful IMO,
+@c and offers nothing that EMACSVER does not.  I guess it relates
+@c mainly to the published book sold by the FSF.  Hence no longer
+@c bother including it except iftex.  Really, I think it should not be
+@c here at all (since anyone can make a pdf version), but should just
+@c be something added by the FSF during the publishing process.
+@c Also, the lispref uses a float (3.0), whereas this uses an ordinal,
+@c so the format is not even consistent.
