        * invoke.texi (Wline-truncation): Document new behaviour.
        * lang.opt (Wline-truncation): Add Init(-1).
        * options.c (gfc_post_options): If -Wline-truncation is unset,
        enable it for free-form source files; for the latter, also use
        -Werror=line-truncation, unless -Wno-error has been specified.
