I was looking into the `get` command, and got tripped up by the `Version` variable. It was unclear to me what Version represents, since it's called REVISION when doing e.g., `helm list`. But even after knowing this, it was not very clear to me why we (implicitly) set the Version variable to 0 but never seem to use it. `mhickey` explained to me on Slack that this gets the latest revision of the release. Makes sense, but I added a comment about that too, to clarify. Signed-off-by: Andreas Lindhé <andreas@lindhe.io>
