Hi,

I noticed when packaging this that when "python" is provided as an input 
(and not python-2), then the python scripts don't get their shebangs 
fixed, because there is no python executable in the $PATH (it is 
python3). This seems not right to me - is there a reason for this, maybe 
so python 2 and 3 can coexist?

In this case the python script was written with python-2 in mind so it 
doesn't matter here though. Thanks in advance for the review.
