revset: add experimental relation and subscript operators...
revset: add experimental relation and subscript operators The proposed syntax [1] was originally 'set{n rel}', but it seemed slightly confusing if template is involved. On the other hand, we want to keep 'set[n]' for future extension. So this patch introduces 'set#rel[n]' ternary operator. I chose '#' just because it looks like applying an attribute. This also adds stubs for 'set[n]' and 'set#rel' operators since these syntax elements are fundamental for constructing 'set#rel[n]'.
