Multiple selection

[CesarAPC]

Hello dgoltzsche, first of all thank you very much for this wrapper.

I'm not familiar at all with Python, so I'd like to ask for your help.
I might be missing something but the multiple selection of packages isn't working.

If I search for something which has 2 or 3 packages that I'd like to install in one go, using "1,2,3" or "1-3" doesn't work, it choses one of those package (apparently) at random (sometimes it selects package number 1, other times 2 or 3).

Hope you can chime in when you have the chance.

Thanks.
