    Fix incorrect IndexOptInfo header comment
    
    The comment incorrectly indicated that indexcollations[] stored
    collations for both key columns and INCLUDE columns, but in reality it
    only has elements for the key columns.  canreturn[] didn't get a mention,
    so add that while we're here.
