re PR fortran/64522 (Free-form source code: -Wline-truncation is no longer enabled by default)

PR fortran/64522
* 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.
