I guess I don't see a downside to supporting more formats. datamash
should support vnlog and csv because 99% of the work is already done and
because this would be beneficial to more people, and would attract more
users. datamash already has a large test suite, so there isn't a lot of
risk of breaking stuff.

vnlog is a part of all my public projects (mrcal in particular), and
internal stuff at JPL (not all me). I'm going to maintain my own patched
datamash for my own use if we decline to merge this, but I'd rather not
have to do that.

I guess the emails with Assaf weren't Cc-ed to the list. I can send them
over if you like, but they don't really matter: the current maintainer
can make his own decisions.

And independent of datamash: if you're the sort of person that does data
processing on the commandline, try out vnl-filter and feedgnuplot. I
promise you'll like them :)
