Subject: Fifth unofficial patch for LESS
Message-ID: <9004022044.AA02118@hudson.cs.columbia.edu>
Date: 2 Apr 90 20:44:42 GMT

A bug in less version 123 with less options "LESS=cw" causes empty lines not to
be cleared properly for short files.  The following patch fixes this:

*** /tmp/,RCSt1a01884	Mon Apr  2 16:35:16 1990
--- line.c	Mon Apr  2 16:33:18 1990
***************
*** 557,568 ****
  		 * If there is no current line, we pretend the line is
  		 * either "~" or "", depending on the "twiddle" flag.
  		 */
! 		if (twiddle)
! 			switch (i)
! 			{
! 			case 0:  return ('~');
! 			case 1:  return ('\n');
! 			}
  		return (0);
  	}

  		 */
! 		switch (i)
! 		{
! 		case 0:
! 			if (twiddle)
! 				return ('~');
! 			return ('\n');
! 		case 1:
! 			if (twiddle)
! 				return ('\n');
! 		}
  		return (0);
  	}
