Increments or decrements the underlying iterator.

Letinner_ andouter_ be the underlying iterators, andparent_ be the pointer to parentranges::join_view, the constant/*ref-is-glvalue*/ bestd::is_reference_v<ranges::range_reference_t<Base>>.

1) Let/*inner-range*/ be:

*outer_, if/*ref-is-glvalue*/==true;
*parent_->inner_ otherwise.

Equivalent to:

auto&& inner_rng=/*inner-range*/;if(++inner_==ranges::end(inner_rng)){++outer_;    satisfy();}return*this;

2) Equivalent to:++*this.

3) Equivalent to:

auto tmp=*this;++*this;return tmp;

4) Equivalent to:

if(outer_==ranges::end(parent_->base_))    inner_=ranges::end(*--outer_);while(inner_==ranges::begin(*outer_))    inner_=ranges::end(*--outer_);--inner_;return*this;
