[Bug-indent] asterix in comment lines can get duplicated

[Richter Rob]

Hoi,
 
'indenting' the following piece of 'comment' results in the given
format:
 
ORG:

        /* Hello
            *
         * dit is de functie header
          *
         */

FORMATTED:

        /*
         * Hello
         * *
         * * dit is de functie header
         * *
         */
        

EXPECTED:

        /*
         * Hello
         * 
         * dit is de functie header
         * 
         */
        

I attached a clumsy attempt to mend this
 
Met vriendelijke groet,
 
Rob
 
PS: used version indent-2.2.9
