[PATCH 1/2] git-svn: Fix for svn paths removed > log-window-size revisions ago

From: Alex Vandiver <alexmv@mit.edu>
Date: May 6, 2009, 20:18 UTC
Message-ID: <1241641133-6974-1-git-send-email-alexmv@mit.edu>

Instead of trying to find the end of the commit history only in the last window, track if we have seen commits yet, and use that to judge if we need to backtrack and look for a tail. Otherwise, conversion can silently lose up to 100 revisions of a branch if it was deleted

>100 revisions ago.
