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

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...

---no-stop-on-copy::
-       Only used with the 'fetch' command.
-
-       By default, git-svn passes --stop-on-copy to avoid dealing with
-       the copied/renamed branch directory problem entirely.  A
-       copied/renamed branch is the result of a <SVN_URL> being created
-       in the past from a different source.  These are problematic to
-       deal with even when working purely with svn if you work inside
-       subdirectories.
-
-       Do not use this flag unless you know exactly what you're getting
-       yourself into.  You have been warned.
