indent: Change comment style on two functions

This is to make those function better readable.

if (foo)
   /* Comment */
   {

   }

is bad style because it requires extra time to notice the begin of the
block and vice versa when noticing the block it is not clear whether
this is an conditioned or unconditioned block.

Having asterisks on the left is better for view impaired people and
for b/w printouts.
