Template for prompt command / "$/%" prefix

[blueyed]

I think it would be nice to include a "$ " or "% " prefix with commands.

I've even tried if it would just handle $ foo to run foo, but display "$ foo", which might be a nice way to do this automatically.

If not doing it automatically it should probably become a config setting so that you do not have to specify/give it every time.

It would also make sense to configure the default directives in a config setting, instead of adding this as a separate/standalone option.

Thanks for posting this. I like the idea of having a prefix as an option in the configs rather than having to specify it for every block. I haven't worked on this project in quite a while, but when I get a chance I'll take a look at the PR :)
