Use Gnulib's `version-etc-fsf' for `--version' and `--help' output.
* m4/gnulib-cache.m4: Add `version-etc-fsf'. Switch to LGPLv3+.
* GUILE-VERSION (PACKAGE): Change to "GNU Guile".
* Makefile.am (distdir): New variable.
* libguile/script.c (scm_shell_usage): Improve formatting. Use
`emit_bug_reporting_address ()'.
(scm_compile_shell_switches): Use `version_etc ()'.
