It could, but the parsing code has no way to communicate that back,
because it's expecting a svn_boolean_t *. (I mean, I suppose it _could_
just not touch the value and rely on the caller to set the default
_first_, but that would be different to how we handle other optional

I think for other cases we may have transmitted a boolean inside an
optional tuple, e.g. (?b). That's a bit sucky, though - it's using the
implementation constraints to drive the interface.
