Hi Will:

I suppose this would be a nice feature to add.  However, I can say that 
I rarely see comments like the first block.  The * ; and %* ; style
comments are really for one-liners, i.e. you are commenting out only
one line of code.  For blocks, it's more likely that you see a single
/* at the beginning and a single */ some lines later.  I see your second
block has them on every line!?!  So, this is an unusual arrangement in
my experience.  I didn't click on the link so maybe there was a very
interesting discussion about why you would want to do something like
this.  However, I don't see people doing that.

Thanks,

Rodney
