1.05
	Fix for xterm.  Save signal mask, ignore SIGCHLD, restore signal mask
	when done.

1.04
	Just added a couple of comments, including one indicating that the
	<defunct> problem has been eliminated.  The other was about the
	downside of UHOH.WAV in fancybell.

1.03
	Another cut at elminiating defunct's.  This time we're waiting for the
	process to exit in the parent.

1.02
	Experimental attempt to eliminate <defunct> processes.  Used signore
	of SIGCHLD.  In retrospect, it's obvious this is a bad idea.

1.01
	Added README with installation instructions

1.00
	First mostly-working version.
