Got the point. I'll make a mental note to mention that in the docs.

I'm switching to "meh" mode: I still think that allowing for the shift  
can lead to some troubles on the user, and I'd be in favor to modify  
_fix_loc_scale or something like that to force loc=0 on discrete  
distributions with support on positive integers, but I'll certainly  
not lose any sleep other that...
In any case, thx a lot to y'all for your comments.
