i would like point out one other way in which trivial patches are problematic: they make it hard to do patches across branches. i have to manually merge a patch because we checked in change into trunk that added accessor functions. accessor functions are great, and i wouldn't be so annoyed if it was part of a larger patch that motivated the need, but it wasn't. it is of course just my opinion, but it is something to think about before we commit a patch.
