I have been using SED for years and never knew that it was possible
to separate commands on the same line with semi-colons.  Thanks to 
Joe Grace for the new information!

In return, I wanted to suggest to people a method I have found for
placing comments in SED scripts.  This works even better in combination

	0i\	This is a commented version of Joe Grace's solution \
		to the problem posed by Susan Maxwell \

	H;	0s** append pattern space to hold space *
	${;	0s** at end of line. . .*
	    x;			  0s** exchange pattern and hold spaces *
	    s@^\(.\)\(.*\)@\2\1@; 0s** Obvious to the casual observer *
	    s@PROMPT>\n>\n<\n@@g; 0s** Equally obvious *
	    s@\n$@@;		  0s** Remove last newline, removing line *
	    p;			  0s** print the pattern space *
	}

Perhaps we can now usher in the era of annotated SED scripts.

Happy stream editing,
Greg Tarsa
