Ah. So that comment doesn't actually get sent as part of a message. That 
was not clear to me.

Yes, yes, I already had a work-around, I was just hoping that it could 
be fixed so that such a work around would not be necessary. To retain 
the philosophical purity of the log file that you want, things would 
have to be rearranged so that these comments were indeed part of the 
MRML messages, and came after the <?xml.. line. Maybe I will have a dig 
around in the code and see how hard this is to do.
