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.
