I expected a horizontal line for "--".

Concerning the separator types, Elisp Info says

  23.18.1.3 Menu Separators
  .........................

  A menu separator is a kind of menu item that doesn't display any
  text--instead, it divides the menu into subparts with a horizontal line.
  A separator looks like this in the menu keymap:

       (menu-item SEPARATOR-TYPE)

  where SEPARATOR-TYPE is a string starting with two or more dashes.

followed by a list of separator types, among them the --double-line I
mentioned.

One can get these from 3rd-party packages. Minion is an example, where
--double-line appears in a popup menu on the mode line.
