Function stringSliceReplaceAt

cmd/docker/aliases_utils.go:23–32

stringSliceReplaceAt replaces the sub-slice find, with the sub-slice replace, in the string slice s, returning a new slice and a boolean indicating if the replacement happened. requireIdx is the index at which old needs to be found at (or -1 to disregard that).
