Seems like a nonissue, unless the XLOG trace makes a subtrans look the
same as a main trans, which it'd not do would it?

We could allow specification of a subtrans ID to be interpreted the same
as specification of its parent main trans.  Dunno if that's actually
useful to anyone.  Actually, I'd think that people would generally
specify recovery up to a particular timestamp, and not be interested in
xact numbers at all ...
