elm 2.2 Patch #3

Summary: This is an official patch for elm 2.2 system.  Please apply it.
Priority: LOW

This fixes a number of bugs with the builtin editor. (1) It used to use
stdio functions and not curses functions to write to the screen causing
the homebrew curses to loose track of where the cursor was - which
showed up when trying to back up over input, (2) the ~m and ~f commands
were nearly completely broken, (3) expanded addresses are displayed
under a wider range of appropriate circumstances, (4) the index screen
needed to be redrawn when the editor is killed by two interrupts. A related
curses bug was also fixed, and user messages in the builtin editor were
made consistent.
From: Rob Bernardo <clib!rob>

Fix:	From rn, say "| patch -p -N -d DIR", where DIR is your elm source
	directory.  Outside of rn, say "cd DIR; patch -p -N <thisarticle".
	If you don't have the patch program, apply the following by hand,
	or get patch (version 2.0, latest patchlevel).

	After patching:
		make
		make install

	If patch indicates that patchlevel is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the patchlevel.h file to find out what has or
	has not been applied.  In any event, don't continue with the patch.

	If you are missing previous patches they can be obtained from me:

+  * Revision 2.15  89/04/24  21:18:45  syd
+  * This fixes a number of bugs with the builtin editor. (1) It used to use
+  * stdio functions and not curses functions to write to the screen causing
+  * the homebrew curses to loose track of where the cursor was - which
+  * showed up when trying to back up over input, (2) the ~m and ~f commands
+  * were nearly completely broken, (3) expanded addresses are displayed
+  * under a wider range of appropriate circumstances, (4) the index screen
+  * needed to be redrawn when the editor is killed by two interrupts. A related
+  * curses bug was also fixed, and user messages in the builtin editor were
+  * made consistent.
+  * From: Rob Bernardo <clib!rob>
+  * 
   * Revision 2.14  89/04/24  19:48:39  syd

+  * Revision 2.30  89/04/24  21:18:49  syd
+  * This fixes a number of bugs with the builtin editor. (1) It used to use
+  * stdio functions and not curses functions to write to the screen causing
+  * the homebrew curses to loose track of where the cursor was - which
+  * showed up when trying to back up over input, (2) the ~m and ~f commands
+  * were nearly completely broken, (3) expanded addresses are displayed
+  * under a wider range of appropriate circumstances, (4) the index screen
+  * needed to be redrawn when the editor is killed by two interrupts. A related
+  * curses bug was also fixed, and user messages in the builtin editor were
+  * made consistent.
+  * From: Rob Bernardo <clib!rob>
