1688RE: [jasspa] re2c and c-hilight, c-mode inside re2c comments

      The .fhook-?.comment variables are used only for the reformatting of
      comments (typically bound to "esc o") and have no effect on either the
      indentation or hilighting rules.

      The hilighting of these comments can easily be changed by the hilight
      command as normal, but the indentation of C files is done by ME's build
      in C styler which is not aware of /*!re2c comments :(
