Subject: [PATCH] 	* listing.c (struct file_info_struct): Rename
 end_pending field to 	at_end. 	(file_info): Initialize at_end, not
 end_pending. 	(buffer_line): If at_end set, just return immediately.  Don't 
 worry about end_pending cases.  Set at_end when EOF is read. 
 (print_source): Check at_end, not end_pending. 	(listing_listing):
 Likewise. PR 6636.
