rsync generally is a more commonly used tool for syncing data - among
others it retains time stamps and is able to remove orphaned files on
the receiver side.

We just need to exclude some directories and a symlink from being
removed as "orphaned", since they originate elsewhere.

maintainer-scripts:
	* update_web_docs_libstdcxx_git: Copy our "inner" documentation
	into the web area using rsync instead of cpio and remove orphaned
	files.

This patch replaces the update_web_docs_libstdcxx_svn script, that
updates online documentation from its sources in the GCC repository, run
once a day from cron, with update_web_docs_libstdcxx_git.

	* update_web_docs_libstdcxx_git: New file.
	* update_web_docs_libstdcxx_svn: Remove.
	* crontab: Use update_web_docs_libstdcxx_git.
