Re: [PATCH resend] Documentation: git-svn: fix example for centralized SVN clone

"Jan Krüger" [off-list ref] writes:

The example that tells users how to centralize the effort of the initial
git svn clone operation doesn't work properly. It uses rebase but that
only works if HEAD exists. This adds one extra command to create a
somewhat sensible HEAD that should work in all cases.

When I first sent this one I said I didn't like the solution all that
much (it would be nicer to use origin/HEAD but we didn't fetch that)
but Eric said he thinks it's okay and the original author of the
section hasn't piped in. It's still better than a nonfunctional example
in any case.

I'll mark this Acked by Eric and apply to 'maint'.  Thanks, both.
