pg_get_functiondef(), trailing spaces and + sign

Is there any direct way in Postgresql to get rid of the frankly anti-useful 
junk at the end of each line (which also infects pg_stat_activity.query), or 
must I resort to sed post-processing?


test=# select pg_get_functiondef(oid)
test-# from pg_proc
test-# where proname = 'foo';
                  pg_get_functiondef
----------------------------------------------------
  CREATE OR REPLACE FUNCTION public.foo(bar integer)+
   RETURNS double precision                         +
   LANGUAGE plpgsql                                 +
  AS $function$                                     +
  begin                                             +
      return bar * 1.0;                             +
  end;                                              +
  $function$                                        +
