Overall, I'm mixed on the results and can see this going one in several directions

Can you elaborate? What do you like/don't like? What potential directions do you see?

• Update available causes the rest of the messages to be indented by quite a bit
• Except for Checking, these are descriptions rather than verbs

@djc I do like this style unification with cargo (I imitate it in my own apps as well from time to time) but I'm afraid without proper JSON output mode this will be fragile... In the long run I imagine the log system can be changed to look more like cargo as well, but I probably won't do that yet in the current version.

I think I'm missing how json output mode is relevant to how things are rendered.
