Thanks Laz! But no instance of Regex I know of will accidently remove some text and REPLACE it with something else on accident.

Um, actually, Regex is quite versatile and capable of doing substitution all day long......

When it was called an error? Why insert new data if it was an error. Of course Regex can replace information, that isn't the point. The point is that this was called an error, mistaking a .* for a \s. That would NOT have inserted new characters. Unless it was deliberate. That's my point.

Regex is brittle, you have to get it right or the results get unpredictable.
