Ah, yes, I forgot I didn't take care of that.  You may notice that the
line starts with |C|.  To reduce the amount of data sent to the
microcontroller the script detects lines that are all comments or
whitespace and doesn't send them.  

When I originally wrote this support I was under the mistaken impression
that comments delimited by parenthesis had the following
characteristics:

1: the start parenthesis had to be surrounded by whitespace (true I
   believe)
2: the end parenthesis had to be surrounded by whitespace (false I
   believe)
3: these comments could span multiple lines, similar to the way that
   C "/* */" comments can (also false I believe)

I forgot to go clean this up when I discovered the problem.  I'll add
that to my list of things to try to get to when I get a chance to work
on the script.  Alas, it doesn't look like that is going to happen this
weekend as I had hoped after all.
