I mistakenly sent the wrong patch for help-fns.el. I sent a patch that added
command `describe-option' and such - something unrelated. Attached are
updated patches wrt today's CVS.

And here's a change log entry:

2008-02-11 Drew Adams  <drew.adams@oracle.com>

	* help.el (describe-key): Joined some split lines to facilitate
filling.
	* help-fns.el (describe-function-1): Fill text of overlong lines.
