CLI Request: Add "--all" option

I’d like to be able to run a command like this:

browserslist --all ">0.5%, last 2 versions, not dead"

And have browserslist return BOTH the list of supported browsers AND the coverage statistics for the US and world, all in one fell swoop. Right now, to get this information, I must run three separate commands:

browserslist ">0.5%, last 2 versions, not dead"
browserslist --coverage ">0.5%, last 2 versions, not dead"
browserslist --coverage=us ">0.5%, last 2 versions, not dead"

I envision that the coverage information could simply be added to the bottom of the list of browsers. To maintain the standard output format:

[browser_name] [space] [version string]

I would suggest formatting the last two “coverage” lines as:

coverage_world [space] 90.34
coverage_us [space] 87.65

This drops the extra text returned by --coverage and allows consumers of the output to still parse it as a newline-separated list of space-separated key-value pairs.

I’ll be using the feature in CodeKit for sure! I don’t have any sort of “CodeKit” account on Twitter though. I just use my personal handle: @bdkjones
