899 suppressing warnings about cases where the guard and body are on
900 the same column, only use the first non-whitespace column in place
901 of the guard token column when dealing with "else" clauses.
902 When rejecting aligned BODY and NEXT, loosen the requirement
903 from equality with the first non-whitespace of guard to simply
904 that they not be indented relative to it.
