[PATCH] Save unmodified buffer when file has been deleted

[Bastien]

If you accidently delete the file while an unmodified buffer is visiting
it, trying to save this buffer will fail because it's unmodified.

This patch fixes this problem.

Let me know if it's okay to commit it (with a proper ChangeLog entry).

Thanks,
