David Rasmussen asks about changing the default values of various
options within Elm for the entire user community.

The easiest way to do this is to;

	1. figure out what elmrc variable corrresponds to what
	   actual variable in the program
	2. change the default accordingly.

The two files in question are ``src/read_rc.c'' for step 1, and
``hdrs/elm.h'' for step 2.  

Let's look at a few examples:

To change "weed" to be OFF by default:

	% cgrep '"weed"' src/read_rc.c
	--------
		  }
		  else if (equal(word1, "weed")) {
		    filter = is_it_on(word2);

	% grep filter hdrs/elm.h
	int filter = 1;			/* flag: weed out header lines?	    */

To change the default - this is where to go.

For "alwaysleave":

	% cgrep '"alwaysleave' src/read_rc.c
	--------
		}
		else if (equal(word1, "alwaysleave") || equal(word1, "leave")) {
		  always_leave = is_it_on(word2);

	% grep always_leave hdrs/elm.h
	int always_leave = 0;		/* flag: always leave msgs pending? */

We can see that it defaults to FALSE. 

Does this make sense?  Would an easier way of setting these defaults
be worth the effort?  If so, how would you like to see it done?
