There have been several reasonable replies to this, but it might be
useful to point out that the ^M is there in the first place because
curl is emitting it.  A quick glance through the curl documentation
doesn't reveal a way to prevent that.  You could strip it off when
postprocessing the curl output in your url-exists function, which
might prevent confusion if you ever use that separately from the
urls-exist wrapper.
