Is "-R" really needed in this case?
I think there is no recursion as you
already found all files. Anyway,
I get the same answers with no "-R".

You are of course right - i just copied the grep and forgot to remove 
"-R" - when you give grep a specific file (which happens in this case) 
"-R" has no effect.
