(exa PR) 1064: Add -A option for more compatibility with ls

ogham/exa#1064

I arrived at an implementation that does what we want and is pretty concise imo

One thing I'd like your opinion on: I think it makes sense to not err when --tree --all --all is used but to fall back to --tree --all.
I find it a bit pedantic for a tool to be very much aware of the problem but not to try and react to it
(I'd do that in a different PR though. does not fall in the scope of this one)

I agree!

Wym by this?

Your changes seem to work without breaking anything, and cargo test works. Testing the -A flag also seems to work for me.

Is this ready to merge?

Well when --tree --all --all is used right now an error is thrown that that is not possible.
But we know why it is not possible (as far as I'm aware): it would lead to infinite recursion.
And we also know a (imo) solution that is reasonable to assume that that is what the user tried to do.
