I would find it more elegant not to special-case the URL field, and just

  my %credential = ('url' => $url);

but I'm fine with your version too.

I started with a version that did that, but there are two complications:

  1. credential_write needs to know that the 'url' field must come
     first, as it overwrites the other fields. So we end up
     special-casing it either way.

  2. Git hands us back the broken-down version, which we add to the
     credential. So it is superfluous to keep sending 'url' for the
     other, non-fill interactions. I don't think it's technically wrong,
     but it also seemed inelegant. Having "credential_write" delete the
     'url' field seemed even more inelegant.

Other than that, and for the 4 patches of the serie:
