//! # Raw command
//!
//! The clap argument the raw IMAP, SMTP and ManageSieve commands take
//! their input from.
//!
//! A command typed on the shell arrives with its backslash escapes
//! literal, so `\r` and `\n` are turned into real CRLF here and a whole
//! batch of commands can be passed inline.
//!
//! The trailing CRLF is each caller's policy: IMAP appends one when
//! missing, io-imap rejecting an unterminated command, where SMTP strips
//! it, io-smtp appending its own, and forbids batching.
