A filesystem::path object cannot be extracted from a stream if the path contain a space

[dgoncharov@…]

e.g.

filesystem::path p;
cin >> p;

If the user enters "asdf asdf" the operator>>() will extract chars until the first space and the path'll be "asdf".

Replacing

is >> str;

in the implementation of operator>>() with

std::getline(is, str);

fixes the problem.
