Comment:

 Ok, as Tomeu suggested, please use a local var.
 {{{
 command = ['/usr/bin/sudo', '-E', '--',
                                        '/usr/bin/rainbow-run
 command = ['sudo', '-E', '--',
                                        'rainbow-run',
 }}}

 This is not really part of fixing the problem I presume. Agreed that it
 might be worth to do so, but please use another patch for this and state
 about it's importance.

 Thanks
