util.human.io: Fix stray 'stty' error by only querying width of real ttys This adds a dependency on a binary and *nix-specific module but then stty is probably *nix-specific anyway so maybe that's fine.

module:log("error", "mod_pep_plus has been renamed to mod_pep, please update your config file. Auto-loading mod_pep...");
module:depends("pep");
