Found out that I would need to extend this some more because if the text is ";;"
followed by space followed by either a series of ";" or "+", or "-", then the
insertion is allowed.  So not just only blanks.

For instance, if the text in a commented string as follows, I will go ahead with
the insertion.

;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
