[datatable-help] Detailed verbose after common data operations?

[Matthew Dowle]

Try options(datatable.verbose=TRUE) globally
or setting the verbose argument in [] syntax for each query.

I don't think it currently prints what you've mentioned, but
the principle is there.

If you provide short examples, and what you'd like printed
in verbose mode, it should be doable.
