Incidentally for Timo: I can find through quick Google search that there are three cases in scripted dialogue...
How embarrassing.

Thanks for the clarifications (and for the rationalizations which sound almost as far-fetched as my usual fare)!
As for those transcript links, Chakoteya's site indeed looks like the most reliable source, and the TNG section there is constantly expanding, too. It's fun to compare the end results with the shooting scripts or earlier script versions found at www.trekcore.com ...
