Both are correct -see below.

It would be straightforward if udom supported all the path operations,
but it would make the interface larger. Instead, udom supports the bare
minimum needed.

This means that if a path is read and then rewritten in
udom, horizontal and vertical lines are converted to absolute line, all
relative commands are converted to absolute, the short forms of cubic
and quadratic beziers are converted to the longer forms.
