//! Stub builtins that accept arguments silently and succeed.
//!
//! These are needed to pass zsh test suite prep blocks that call
//! commands like `autoload`, `zmodload`, `integer`, `float`, `let`,
//! `trap`, `hash`, `disable`, `enable`, `emulate`, `zle`, `bindkey`,
//! `compdef`, `zstyle`, `alias`, `unalias`, `builtin`, `wait`, `fg`,
//! `bg`, `jobs`, `suspend`, `times`, `umask`, `ulimit`, `getopts`,
//! `pushd`, `popd`, `dirs`, `limit`, `unlimit`, `sched`, `rehash`,
//! `noglob`.
