bug#20256: 25.0.50; css-mode: filling multi-line comments

[Simen Heggestøyl]

Filling multi-line comments in `css-mode' is broken. Consider for

instance the following comment:

  /*

   * Multi-line comment here.

   * This comment spans

   * multiple

   * lines.

   * Better fill it!

   */

Filling it with a `fill-column' of 70, I'd expect the following

result:

  /*

   * Multi-line comment here.  This comment spans multiple lines.

   * Better fill it!

   */

But as of now, what we get is this:

  /* * Multi-line comment here.  * This comment spans * multiple *

  lines.  * Better fill it!  */

From this comment in `css-fill-paragraph', it sounds like it is

supposed to work, or has been working some time before:

  ;; Filling inside a comment whose comment-end marker is not \n.

  ;; This code is meant to be generic, so that it works not only for

  ;; css-mode but for all modes.

Could someone fill me in?

Alternatively, we could let `css-mode' borrow comment filling code

from `cc-mode', like `js-mode' and `js2-mode' do. Please let me know

if that would be an acceptable fix.
