[Jprogramming] assert verb from stdlib mismatches assert. control

[Igor Zhuravlov]

stdlib has the definition:
   assert=: 0 0 $ 13!:8^:((0 e. ])`(12"_))
which accepts a wrong input e.g.
   assert 1 2 1
                       NB. an error expected, not an empty output

This definition may be fixed as:
   assert=: 0 0 $ 13!:8^:((1 +./@:~: ])`(12"_))
to match (assert.) control behavior:
   assert 1 2 1
|assertion failure: assert
|       assert 1 2 1
