4518 flatten({list} [, {maxdepth}]) *flatten()*
4519 Flatten {list} up to {maxdepth} levels. Without {maxdepth}
4520 the result is a |List| without nesting, as if {maxdepth} is
4521 a very large number.
4522 The {list} is changed in place, make a copy first if you do
4523 not want that.
4524 *E964*
4525 {maxdepth} means how deep in nested lists changes are made.
4526 {list} is not modified when {maxdepth} is 0.
4527 {maxdepth} must be positive number.

4529 If there is an error the number zero is returned.
