I have no argument with Bill's note, he simply collected the right
thread of conversation to knock me off the fence I was sitting on.
It seems that using grep as a filtering process in a pipeline would
be severely hampered by using this "binary file" interpretation.
Consider the following case:
grep foo ./* | grep bar | ...
If we are concerned about not breaking scripts that use the assorted
options to tar (the pax vs. GNU Tar debate), how about scripts using
the above construct, or its moral equivalent...
