Suggestion: add the possibility to apply multiple operations to a single column (or multiple columns)

[Tomas Peitl]

Hi everyone,

My suggestion is to make it possible to write

datamash mean,max,count 2

instead of

datamash mean 2 max 2 count 2

i.e. to remove the repetitiveness in the field identifier when multiple 
operations are needed on the same field. Of course, it doesn't have to 
be just a single field, you could also do

datamash mean,max,count 1-2,4 perc 2-3

or anything like that.

Cheers,
Tomas
