The problem is, we get the same exit status when grep either:
	-cannot append to the file
	-does not find any matches

(It's 1 both times)  The problem is that the error is not a grep error and
comes from the shell (>>), so grep doesn't know.

...or did I misunderstand?

I know of ways to do this, but they are not pretty :\
