importPrefix in format.go computes the end of the package statement including a trailing newline. This causes a panic if the user has not typed the newline. The code now checks for that case. Fixes golang/go#40208 Change-Id: I4c5118a5de78027e6c5e6ed91dfddca81e38f7e9 Reviewed-on: https://go-review.googlesource.com/c/tools/+/242638 Reviewed-by: Heschi Kreinick <heschi@google.com>
