/**
* Examines the string and returns whether we're inside a double quote.

* This is used to decide whether we should put an automatic space before or after a double
* quote character. If we're inside a quotation, then we want to close it, so we want a space
* after and not before. Otherwise, we want to open the quotation, so we want a space before

* "minutes" use cases is dominant after digits.
* In the practice, we determine whether we are in a quotation or not by finding the previous
* double quote character, and looking at whether it's followed by whitespace. If so, that
* was a closing quotation mark, so we're not inside a double quote. If it's not followed
* by whitespace, then it was an opening quotation mark, and we're inside a quotation.
