Quell clang warning from adat.c

Comment out the conditional:

                    if( pCmd->pacCmdStrs != NULL )

as the structure does not have a terminating NULL, this expression will
never evaluate to false.  Should the structure assigned be modified to
have a NULL as the last element, then uncomment these lines to restore
the test.
