Commands.js doesn't list any exported constants

[peterflynn]

http://brackets.io/docs/current/modules/command/Commands.html is basically blank. Ideally it would list all the constants that are exported.

This seems to be working for other modules, though -- e.g. Menus does include things like BEFORE in the output.

Maybe the difference is that in Commands, it's assigning literals directly to exports.FOO, while in Menus there's an intermediate var declaration?
