Yes I know.  However we really need to be able to "look around" in these
files so several greps might be neccessary.  Reformatting the entire 
file before each grep is slow - and a temporary file takes up too much disk
space.  There doesn't seem to be a good solution.  There are many ways to 
do this but none are very good.
