* src/c++17/fs_path.cc (path::_List::operator=(const _List&)): Fix
reversed arguments to uninitialized_copy_n.
* testsuite/27_io/filesystem/path/assign/copy.cc: Check that source
is unchanged by copy assignment.
* testsuite/util/testsuite_fs.h (compare_paths): Use std::equal to
compare path components.
I should have used the three-argument version of std::equal, because
the four-argument one is not available in C++11.
Fixed with this patch, tested powerpc64le-linux and committed to
trunk. This needs to be backported togcc-9-branch too.
