[PATCH] contrib/git-svn: remove the --no-stop-on-copy flag

[Eric Wong <normalperson@yhbt.net>]

Output a big warning if somebody actually has a pre-1.0 version
of svn that doesn't support it.

Thanks to Yann Dirson for reminding me it still existed
and attempting to re-enable it :)

I think I subconciously removed support for it earlier...
