Feature: Open file picker by default when the specified path is a directory

[vv9k]

I would like to see the contents of a directory when opening hx with a path to directory like:

hx /tmp

Shows me file picker with the contents of /tmp.

I would like to give a try at implementing this.

I like this idea, but I wonder what the behavior should be if several files/folders are listed, i.e. hx /tmp log.txt

That's also what I currently stumbled upon. I'm wondering how to handle this with what there is available now.

You should be able to reuse the file picker code here:

helix/helix-term/src/commands.rs

Lines 1083 to 1085 in 2719a35

	let root = find_root(None).unwrap_or_else(|| PathBuf::from("./"));
	let picker = ui::file_picker(root);
	cx.push_layer(Box::new(picker));

You would need to construct it if necessary, and compositor.push it right after the editor here:

helix/helix-term/src/application.rs

Lines 48 to 56 in 2719a35

	if !args.files.is_empty() {
	for file in args.files {
	editor.open(file, Action::VerticalSplit)?;
	}
	} else {
	editor.new_file(Action::VerticalSplit);
	}
	compositor.push(Box::new(ui::EditorView::new()));

Already got that figured out, I'm wondering what to do with the extra arguments aftrer initial directory path like hx /tmp some_file - what to do about some_file there. Perhaps all extra files should be opened as splits?

And also what to do when there is more than one directory like:

hx /tmp /home some_file

I added initial changes in #59
