Why do you need to? Check for the beginning of the string BEFORE the
set brackets. The point of set brackets is "match from a set of
chars". Since "beginning of string" can only match one place, it has no
meaning as a member of a set. Or in other words, if it has meaning, it
needs to be matched FIRST out of the set, and therefore you can just
remove from the set and put before the set brackets.
