--- Comment #5 from Alexandre Julliard julliard@winehq.org --- (In reply to Robbert van der Helm from comment #4)
I've created a separate issue for (1) (bug 50879), and I've added a comment to bug 50867 for (3). (4) is probably not a bug but more of an unintional consequence of this change, right? Or would `wine 'https://google.com%27%60 cause `iexplore` or something to pop up?
Yes, that's intentional. It may not be all that useful with a URL, but it lets you run a .msi file directly for instance.
