Are ToExpression::sntx warnings ok for CodeParse to issue?

[arnoudbuzing]

Not sure if this is an obscure failure for CodeParse, or if CodeParse can legitimately issue ToExpression warnings:

This is a good catch!

I was escaping other characters so that something like this was fine to do:

<<[\b\f\n\r\t]

but was not handling double quote.

Addressed in https://github.com/WolframResearch/codeparser/pull/15

Obscure failures are CodeParser's currency
