Fix cosmetic blemishes involving rd_createSubid.
Remove an obsolete comment from AtEOXact_cleanup(). Restore formatting
of a comment in struct RelationData, mangled by the pgindent run in
commit 9af4159fce6654aa0e081b00d02bca40b978745c. Back-patch to 9.5 (all
supported versions), because another fix stacks on this.
