With adaptive-wrap, in a LaTeX-mode buffer, commented out lines that start with a "-" or a "*" get those symbols at the start of each of the wrapped lines. That does not happen with other symbols such as "+" or "=".

The desired behavior would be to only have the percentage sign plus some whitespace added to the wrapped lines. For example as in

This was originally reported for the "virtual-auto-fill" package:
As commented there, this might be hard to fix; maybe the "%" could be detected as special (a comment char), and the magic list processing added on top of that.

Steps to reproduce:

- Start emacs with emacs -Q

- Evaluate
  (require 'package)
  (use-package adaptive-wrap)

- Create a new tex buffer and ensure it is in latex mode

- Type some suitable long text in a single line with "%%" as first character (comment),  then a space, then a "-". For example:

  %% - aaaaa eeeee iiiii ooooo uuuuu aaaaa eeeee iiiii ooooo uuuuu aaaaa eeeee iiiii ooooo uuuuu aaaaa eeeee iiiii ooooo uuuuu aaaaa eeeee iiiii ooooo uuuuu

- Enable adaptive-wrap-prefix-mode

- Modify window size so the text is displayed in multiple lines.

- Change the "-" by a "*", a "+", a "=".
