I am at great risk of falling into a bike shed[1] here. If grep
works fine and all is happy then we get a zero return value. All
other possible situations *should* return a non-zero error status
that helps silly old UNIX people like me.
If someone needs to write if-then-else-what? clause stuff in code
then that is correct behavior. Why fix that which works fine?
