I inherited a program that was not working properly, and after some digging around I found a long commented line, which extended beyond the right edge of the screen, which had a semi-colon at the end with an uncommented line of code on the next line. The problem was that the semi-colon continued the comment to the next line. Is that normal behavior? I know that semi-colon extends a line to the next physical line, but I didn't know that included commented lines too. So, in the following...

That's normal, though tricky, behaviour.
