Enum ShellPause 

pub enum ShellPause {
    Always,
    OnError,
    Never,
}

When Trail prints the result block and waits for a key before reclaiming the screen from a command.

Without a pause, run_external re-enters the alternate screen the instant the child exits, so the output of !ls is painted and erased in the same breath. The editor is the reason this is a choice rather than always on: nobody wants to press Enter after closing their editor.

Variants

Always

Always wait — the default for !<command> and :git.

OnError

Wait only when the command exited non-zero, or could not be run at all.

Never

Never wait. Used for the editor and for OS-handler opens, whatever the configured policy is, since those draw their own screens.
