comand line quoted parameters don't work

I wrote a simple test por pass user parameters by command line in Windows. For one-word parameters it works ok, but when I quote parameters to include spaces in values, sikulix is ignoring my quotes. In fact it treats quotes as part of each parameter, as it does to any other character.

The command line used is like this:
<path>runsikulix.cmd -r <path to script.sikuli> -- 'par 1' 'par 2'

My script is this:
import sys
for arg in sys.argv:
    print arg
popup("see what u got.")

The result is this:
'par
1'
'par
2'

So, I conclude that sikulix treated my command line as containing 4 parameters.

I'm using Sikulix 1.1.0 Build: 2015-09-15_01:00nightly
