This makes it a lot clearer, with no perl, no sed, no eval.  It does
become louder, but should be easier to follow in general ...

... except for a magic like this one.

We may remember the REMOTE_URL -> $remote_url trick used here this

But overall I think this makes it simpler.  I am not 100% sold on
the necessity of lengthy earlier steps, though.

Thanks.
