Yes, this is rather an easy way out and its variants have been
attempted over the years for a few times, I think.  Marking a root
commit differently from others, like the hard break line immediately
below it, drawing it with something other than '*', or painting '*'
in red---any of these approaches will let you tell that the commit
does not have a parent-child relationship with the commit that
appears on the next line.

But the reason why the user asks for "--graph" is because they want
to see the parent-child relashionships in the graph layout itself by
laying commits out on the 2-D plane, and drawing the root so
differently from others is failing that task.
