All boolean options (such as -O, -I, -v etc), both short and long versions,
  now always switch on/enable the option named. Using the same option multiple
  times thus make no difference. To switch off one of those options, you need
  to use the long version of the option and type --no-OPTION. Like to disable
  verbose mode you use --no-verbose!

- Added --remote-name-all to curl, which if used changes the default for all
  given URLs to be dealt with as if -O is used. So if you want to disable that
  for a specific URL after --remote-name-all has been used, you muse use -o -
  or --no-remote-name.
