Hmm, that may be an issue, I would think.

work in this case?
I also wondered if this is easier to read:
pipe | stdin_contains m2 && ! pipe | stdin_contains master
but I do not think it is (we cannot say "pipe | ! stdin_contains master").
In any case, here is what I ended up queuing. Thanks.

This is useful if you forgot to restrict the diff to the paths you want to see, or selecting precisely the ones you want is too much typing.
[jc: with a change to return from the function upon 'n' by Charles Bailey and a small tweak in stdin_doesnot_contain() in the test]
