From 5b16b3c0157eb3abfb9237f3c5eaa89ac0d6c6c6 Mon Sep 17 00:00:00 2001
From: Karl Berry <karl@gnu.org>

Subject: [PATCH] 	* texinfo.tex (\begindoublecolumns): Ship out
 \partialpage 	immediately if it is nonvoid, instead of saving it.  This
 avoids a 	bug where the index could end up printing one line per page
 (see 	the indexspread.tex test). 	From: Andreas Schwab
 <schwab@issan.informatik.uni-dortmund.de>

	* texinfo.tex (\image): If running pdftex, do \pdfimage{imagefile.pdf}.
 	From: Samuel Tardieu <sam@inf.enst.fr>

 	Also, update copyright year.
