(https://github.com/ruby/irb/pull/473) * Handle file loading commands' argument error gracefully Currently, if users don't provide an argument to `source`, `irb_load`, and `irb_require`, IRB raises `ArgumentError` with full stacktrace. This is confusing because it looks similar to when IRB has internal issues. The message also isn't helpful on helping users avoid the error. So in this commit, I add a new `CommandArgumentError` for commands to raise explicitly when users' input doesn't satisfy a command's argument requirement. * Gracefully handle `fg` command's argument requirement
