This is an historical mistake.

setsearch should have be defined as returning

setsearch(S,x,0)-setsearch(S,x,1) (with current notation).

instead of having a flag.

We fixed the C interface but not the GP interface:

    16- gen_search / vecvecsmall_search: remove flag

    the result is now positive if the element is found else -i if element
    should be inserted at position i.
