Sorry for the latency[1], ack on both of Karl's patches for post-1.5.4.

Here's a conservative change for 1.5.4 (not at all tested):

From dbccd8081c6422569a9ca1211e27f56a24fdf3f3 Mon Sep 17 00:00:00 2001
From: Eric Wong <normalperson@yhbt.net>
Date: Mon, 21 Jan 2008 14:37:41 -0800
Subject: [PATCH] git-svn: default to repacking every 1000 commits

This should reduce disk space usage when doing large imports.
We'll be switching to "gc --auto" post-1.5.4 to handle
repacking for us.
