At least a dozen people have sent me alternate ways of doing this, the 
most obvious using 'nm'.  Look, I KNOW ABOUT NM! But you're missing the 
point - suppose the item in the .o files was another type of string, e.g.
an error message.  

The point is:  There are some files.  One or more may contain a string in
which I am interested.  grep -l is a tool which is supposed to tell me whether
one or more files contain a string.  The fact that it refuses to do so for 
a class of magic files is a gratuitous violation of the unix paradigm.
