Isn't the entire purpose of using a default value of `mail-foo' to pick
up any user customizations of mail-foo in .emacs (otherwise it'd be easy
enough to just use a literal "> " as a default for message-yank-prefix)?

So if the user sets mail-yank-prefix to "   ", but your (acceptable ...)
test rejects that because it looks wrong, then the purpose has (to some
extent) been defeated...
