Add some missing backslash commands to psql's tab-completion knowledge.

tglsfdc · tglsfdc · commit f1175556a17a · 2017-06-03T17:10:25.000-04:00
\if and related commands were overlooked here, as were \dRp and \dRs from the logical-replication patch, as was \?. While here, reformat the list to put each new first command letter on a separate line; perhaps that will limit the need to reflow the whole list when we add more commands in future.
