(parse_args): remove erroneous pointer dereference

of i when gobbling whitespace.
(init_user_commands): set second argument to "alias" command to
arg_REST.
(init_user_commands): likewise for "set"
(cmd_readkey): remove useless PRINT_DEBUG
(cmd_set): pass an empty string to parse_args when the args[1] is
NULL.
(cmd_set): call the set function if the arg list size is 0.
