Of course, the match expressions can be changed as easily as the shell
script line.  

It seemed like you had been caught by IFS.  And if you're trying to
include that snippet in a larger script, IFS will catch you again.

If you want to avoid the IFS change affecting more than just the read,
you can use it like this:
	while IFS="" read l
	do
		case "$l" in
			"completely suppress this line")                     ;;
			"A line to blank out")                  echo ""      ;;
			"---------------------")                echo ""      ;;
			*)                                      echo "$l"    ;;
		esac
	done

a.
