Certainly. Some initial testing reveals that getPreviousTokenAndStart is not in conflict with this approach as I had feared, because Lexer::GetBeginningOfToken will include an escaped newline immediately followed by non-whitespace as being part of the token.

I see no failing existing tests with just the new change to getRawToken, so I will update this PR to take that approach.
