bug#14790: An issue building Emacs (trunk) manual

[Angelo Graziosi <angelo.graziosi@alice.it>]

Usually I build Emacs PDF manual applying this patch:

diff -Naur emacs.orig/doc/emacs/emacs.texi emacs/doc/emacs/emacs.texi
--- emacs.orig/doc/emacs/emacs.texi	2012-01-15 18:59:57.942500000 +0100
+++ emacs/doc/emacs/emacs.texi	2012-02-05 21:32:51.656250000 +0100
@@ -1,5 +1,7 @@
  \input texinfo  @c -*- coding: utf-8 -*-

+@afourpaper
+@setchapternewpage odd
  @setfilename ../../info/emacs
  @settitle GNU Emacs Manual

it generates the PDF in A4 format and opens chapters on odd page.

Now, say after r. 113247 (a few days ago), building the PDF produces 
some "harmless" errors (the PDF is created) which one doesn't like to see:

$ make emacs.pdf 2>&1 | tee ~/work/emacs_pdf_a4.log

$ grep -i error ~/work/emacs_pdf_a4.log
@textrm (@texttt compilation-next-error[]@textrm ) and @texttt M-p[] 
@textrm (@
texttt compilation-previous-error[]@textrm ) to move to
@textrm (@texttt compilation-next-error[]@textrm ) and @texttt M-p[] 
@textrm (@
texttt compilation-previous-error[]@textrm ) to move to
@textrm (@texttt compilation-next-error[]@textrm ) and @texttt M-p[] 
@textrm (@
texttt compilation-previous-error[]@textrm ) to move to
@textrm (@texttt compilation-next-error[]@textrm ) and @texttt M-p[] 
@textrm (@
texttt compilation-previous-error[]@textrm ) to move to

Instead without the patch, no error is catched:

$ make emacs.pdf 2>&1 | tee ~/work/emacs_pdf_us.log

$ grep -i error ~/work/emacs_pdf_us.log
EMPTY

Could this be related to the recent changes introduced with rev. 113268? 
(different doc/*.texi files were changed...)

Could you add an option to build emacs.pdf in A4 format etc.?


TIA,
