[CM] snd arithmetics -> odd numbers - locale thing?

Indeed.  If i do

$ LC_NUMERIC="C" snd

it behaves normally, ie. (/ 3 2.0) = 1.5

I could wrap snd into this.  But having this dependent on locale
settings would presumably make strange errors for many users, so perhaps
better to find another way to print things.

It makes problems where the bogus number returned is used 'literally',
ie. stored in markov-tables etc.
