That's the real question: whether or not `.' should match @(?|.?), even when dotglob is enabled (and yes, both patterns have to be in there). There isn't really any other. Since it doesn't match ? when dotglob is enabled, there's an obvious inconsistency there, and that's what I'll look at.
---- I don't see it as being inconsistent, since shopt -u dotglob will match the literal 1st byte (dot). From there we are no longer looking at "default behavior for "." to match '?' but at normal "glob-RE" rules. .foo won't be match by ????, but will be matched by .??? Note, it's not just about . and .., all files starting with 1 or 2 dots.
