I run wnewmail in a small window at the bottom of the screen.
When I read my inbox, I like to have that window cleared so that
the only message headers displayed are those arriving since I last
read mail.  In my environment (Apollo) that can be done simply
by writing a form feed to the window.

A very easy, but far from "correct" solution, is to clear the
window whenever the inbox shrinks.

This doesn't work at all when:
   1. reading messages does not result in their deletion from the in folder.
   2. when you are watching multiple in folders.

However, it does do pretty much what I want (I'm not yet using filter).


For Elm2.3 PL5, the diffs are:

*** utils/newmail.c.orig	Thu Jul 26 14:05:14 1990
--- utils/newmail.c	Thu Jul 26 14:22:37 1990
***************
*** 264,269 ****
--- 264,272 ----
  	      } 
  	        
  	      folders[i].filesize = newsize;
+ 
+ 	      if (in_window && !debug && (total_folders == 1))
+ 		printf( "%s messages read.\n\fIncoming mail:\n", newsize == 0 ? "All" : "Some" );
  	    }
  	  }
