> Some duplication that could be extracted to a function?

I wondered as much, too, but this is really trivial code. Also, if this
gets to be a function, then that would have to be used using shell
expansion, like:

    url="$(canonical_url "${url}")"

which does not look very nice either.

So I believe duplication is acceptable in this case.
