If a path has ".." components, the abspath() result may be wrong if it
resolves them by removing a parent symlink. The absolute() method of
pathlib.Path does this right by retaining ".." components.
>>> os.path.abspath('/foo/symlink/../bar')
'/foo/bar'
>>> pathlib.Path('/foo/symlink/../bar').absolute()
PosixPath('/foo/symlink/../bar')
abspath() is also the wrong choice if we're computing the target path
for a relative symlink via relpath(). A relative symlink is evaluated
from the parsed path of its parent directory.
