Emacs' interactive commands are not TAB completed like Evil commands.
Evil nicely supports running Emacs commands after pressing colon ":", but if you type, say, ":other-w" and hit TAB, you'd expect it to try and auto-complete its own commands along with Emacs own commands. In this case "other-window". This is how M-x currently handles it in Emacs.
Are there any plans to support this, or maybe pointers to the relevant part of the code?
