Crash on pg_ctl initdb without options

pg_ctl initdb crashes if no options are passed.
Do we need additional if-null test for pgdata_opt just like post_opts?
   $ pg_ctl initdb   sh: -c: line 0: syntax error near unexpected token `null'   sh: -c: line 0:
`"/usr/local/pgsql/bin/initdb"(null)'   pg_ctl: database system initialization failed
