That's true. Patches welcome to improve that. Maybe we can define that
if the stored password string starts with $1$md5$ and has a just the
right length then it's a md5 hash rather than cleartext, or something
I do fear that people are going to look at the file and say "hey, it's
encrypted [sic] so it's secure! I can share the file with the world!".
