1. Create or open an encrypted text file, which has .gpg suffix.
2. Save the file with DOS-eol. (C-x RET f utf-8-dos and C-x C-s)
3. Kill buffer and re-open it.

I can see ^M garbage in each eol.  I noticed it because Wanderlust (a
mailer) failed to verify signature on Windows.  Attached patch can
resolve the issue.
