Yes, there are many ways to fix this but some are as unexpected as the coloring problem itself:
   -you can hit return twice above the red text
   -you can hit back space below the red text
   -you can scroll the window

Not every case can be handled this way though. For example, if you want to uncomment part of previously commented text, the only choice is to break the comment with a return.

Regardless, what I had not realized until just now is that it is only the color of the line that is affected, i.e., the red text is *not* treated as a comment during typesetting, as I had thought when I sent the message. This makes the whole thing a lot more benign that I had feared.
