Andrew Gallant 231643248b syntax: fix bug when parsing ((?x)) ...

This fixes yet another bug with our handling of (?flags) directives in
the regex. This time, we try to be a bit more principled and
specifically treat a (?flags) directive as a valid empty sub-expression.
While this means we could remove errors reported from previous fixes for
things like `(?i)+`, we retain those for now since they are a bit weird.
Although `((?i))+` is now allowed, which is equivalent. We should
probably allow `(?i)+` in the future for consistency sake.

Fixes #527
