[Yuan Fu]

branch: emacs-29
commit a760364f5f36ad4ded67b0fd5ca4ef59c9b2d705
Author: Yuan Fu <casouri@gmail.com>
Commit: Yuan Fu <casouri@gmail.com>

    Fix c-ts-mode--fill-paragraph
    
    Example:
    
           doc: /* Return non-nil if NODE1 and NODE2 are the same node.
    If any one of NODE1 and NODE2 is nil, return nil.
    This function uses the same equivalence metric as `equal'.  */
    
    * lisp/progmodes/c-ts-mode.el (c-ts-mode--fill-paragraph): Fix the
    case where there are words before the /*, like the example above.
