Fix issue reported from @ttys3

[ttys3]

just tested cb206ae
the order is back to normal

but still a small problem: newline after one line import will be stripped

for example:

input:

package svc

import "google.golang.org/protobuf/proto"

// GetFoo do things
func GetFoo() {
  // body
}

buggy output (the newline after import "google.golang.org/protobuf/proto" is gone):

package svc

import "google.golang.org/protobuf/proto"
// GetFoo do things
func GetFoo() {
  // body
}
