dvc diff support for -R, --recursive

[garylschultz]

I'm using dvc for a project that has all of my original data under git/dvc control in a data/ directory, and am using pipelines and the dvc repro command. This tool rocks!

I would like to look at which of my data/ contents have changed from one commit to another. However, I don't know how to restrict the dvc diff command to look at just the data/ directory. There are so many items in the pipeline that it is difficult to see what I'm interested in.

It would be really nice to just say dvc diff -R data/

Thanks in advance for considering this.

@garylschultz aren't you looking for: #3388 ?
I guess -R is not exactly it, but I guess they are related.

[garylschultz]

Thanks. They do seem related.

If targets would apply to all .dvc files in a specified directory, then that would solve my problem. So targets are probably the best solution.
