git-svn: Warn about changing default for --prefix in Git v2.0

Browse Source 
In Git v2.0, we will change the default --prefix for init/clone from
none/empty to "origin/" (which causes SVN-tracking branches to be
placed at refs/remotes/origin/* instead of refs/remotes/*).

This patch warns users about the upcoming change, both in the git-svn
manual page, and on stderr when running init/clone in the "multi-mode"
without providing a --prefix.

WARNING: --prefix is not given, defaulting to empty prefix.
This is probably not what you want! In order to stay compatible
with regular remote-tracking refs, provide a prefix like
--prefix=origin/ (remember the trailing slash), which will cause
the SVN-tracking refs to be placed at refs/remotes/origin/*.
NOTE: In Git v2.0, the default prefix will change from empty to 'origin/'.
