The thing I would like to see with grep is to have it optionally give me a 0 return code if it doesn't find anything.

I know why the authors chose to use a non-zero return code as the default, but when I'm using grep deep in a pipeline and doing my own checking of the results to see if nothing was found, I don't need grep bombing out the whole pipeline with a non-zero return code.

The alternative of being forced to use "(grep pattern||true)" instead of a plain "grep -q" is kinda painful.
