* common/iobuf.c (direct_open): Add arg MODE700. (iobuf_create): Ditto. * g10/openfile.c (open_outfile): Add arg RESTRICTEDPERM. Change call callers to pass 0 for it. * g10/revoke.c (gen_desig_revoke, gen_revoke): Here pass true for new arg. * g10/export.c (do_export): Pass true for new arg if SECRET is true. -- GnuPG-bug-id: 1653. Note that this works only if --output has been used.
