Two questions.

 - What if a user has SVN_SSH exported _and_ wants to use a different one
   from the one s/he uses for git?  Naturally such a user would set both
   environment variables and differently, but this seems to override the
   value in SVN_SSH;

 - Can a user have SVN_SSH exported, on MSWin32 or msys, and use svn
   outside git?  If so, what does the value of SVN_SSH look like?  Does it
   typically have necessary doubling of backslashes already?

What I am getting at is, if the patch should look something like this
instead:

	if (! exists $ENV{SVN_SSH}) {
		if (exists $ENV{GIT_SSH}) {
			$ENV{SVN_SSH} = $ENV{GIT_SSH};
			if ($^O eq 'MSWin32' || $^O eq 'msys') {
                               $ENV{SVN_SSH} =~ s/\\/\\\\/g;
			}
		}
	}
