TODO: consider file name from the redirected URL with -O ?

It isn't easily solved, but with some thinking someone could probably
come up with a working approach?

+18.17 consider file name from the redirected URL with -O ?
+
+ When a user gives a URL and uses -O, and curl follows a redirect to a new
+ URL, the file name is not extracted and used from the newly redirected-to URL
+ even if the new URL may have a much more sensible file name.
+
+ This is clearly documented and helps for security since there's no surprise
+ to users which file name that might get overwritten. But maybe a new option
+ could allow for this or maybe -J should imply such a treatment as well as -J
+ already allows for the server to decide what file name to use so it already
+ provides the "may overwrite any file" risk.
+
+ This is extra tricky if the original URL has no file name part at all since
+ then the current code path will error out with an error message, and we can't
+ *know* already at that point if curl will be redirected to a URL that has a
+ file name...
