I cut this one into 2 pieces:
    c) the whole output file is empty
    d) the whole output file just contains only white spaces

I just uploaded 1.3a802 which implements the following syntax:
above [a-d] cases are handled by resp. u, w, z and s modifiers,
and are postfixed by a number:
    0: output is processed as usual
    1: this sliceset is skipped
    2: stop processing
These flags may be combined, e.g.
    #u1w2z1s0

I agree this is not very user-friendly, improvement are welcome ;)
