Fix some issues I noticed while fooling with an extension to allow an additional kind of toast pointer. Much of this is just comment improvement, but there are a couple of actual bugs, which might or might not be reachable today depending on what can happen during logical decoding. An example is that toast_flatten_tuple() failed to cover the possibility of an indirection pointer in its input. Back-patch to 9.4 just in case that is reachable now. In HEAD, also correct some really minor issues with recent compression reorganization, such as dangerously underparenthesized macros.
