The commit message has to be amended to comply with our guidelines (prefix: imperative verb) before this can land :)

Is this semver-minor since it changes the public API? In any case, I think it makes sense to document the change in behavior. I assume the right place is to add a changes: block here:

node/doc/api/buffer.md

Lines 1711 to 1715 in 269175b

### `buf.copy(target[, targetStart[, sourceStart[, sourceEnd]]])`
