doc: Clarify use of _ccnew and _ccold in REINDEX CONCURRENTLY

Invalid indexes are suffixed with "_ccnew" or "_ccold".  The
documentation missed to mention the initial underscore.
ChooseRelationName() may also append an extra number if indexes with a
similar name already exist; let's add a note about that too.
