[Bug-datamash] Control the decimal separator

[Magnus Göransson]

Hello,

I used LC_NUMERIC environment variable to control decimal separator, for 
example:

export LC_NUMERIC=sv_SE.UTF-8

In my bash-script solved the problem that my decimals (",") was 
incorrectly interpreted when the script was running from crontab where 
the environment is very limited. The error from datamash was "invalid 
numeric value in line" due to the wrong interpretation.

/Best regards
