Yehuda Katz 0dc4b2b686 Add support for external escape valve (^dir) ... This commit makes it possible to force nu to treat a command as an external command by prefixing it with `^`. For example `^dir` will force `dir` to run an external command, even if `dir` is also a registered nu command. This ensures that users don't need to leave nu just because we happened to use a command they need. This commit adds a new token type for external commands, which, among other things, makes it pretty straight forward to syntax highlight external commands uniquely, and generally to treat them as special.		2019-08-15 15:18:18 -07:00
