From 02c48cd69b3ebfac3867f0f9ceb1503a5af118fc Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 25 Jun 2009 22:48:28 -0600 Subject: [PATCH] fast-export: Omit tags that tag trees Commit c0582c53bcf4e83bba70e1ad23abbad31f96ebc8 introduced logic to just omit tags that point to tree objects. However, these objects were still being output and were pointing at "mark :0", which caused fast-import to crash. This patch makes sure such tags (including deeper nestings such as tags of tags of trees), are omitted.
