Comment 2 for bug 487083

Two things more:
4. The script shows the comparison even when the two versions are identical. I think it should say explicitly 'files are identical' or better do not ask any questions.
5. Titles and labels say that the script is going to do something about the grub itself (e.g. keep current version). This way I'm not informed if it will keep the current version of configuration or binaries or both. This needs clarification.
