[issue15509] webbrowser.open sometimes passes zero-length argument to the browser.

[Anton Barkovsky]

New submission from Anton Barkovsky:

Because of the way webbrowser.UnixBrowser.open generates command-line
arguments the resulting list sometimes looks like this:

  ['chromium', '', 'http://www.example.org/']

This seems to work fine with chromium for me but as you can see:

  >>> subprocess.call(['ls', '', '-l'])
  ls: cannot access : No such file or directory
  2

It's not a good idea to rely on that.
I'm attaching a patch that filters out those empty arguments.
