From 50fd9bd8430a957ea6c6674ce6112f375985abbc Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 14 May 2008 18:03:31 +0100 Subject: diff options: Introduce --ignore-submodules The new option --ignore-submodules can now be used to ignore changes in submodules. Why? Sometimes it is not interesting when a submodule changed. For example, when reordering some commits in the superproject, a dirty submodule is usually totally uninteresting. So we will use this option in git-rebase to test for a dirty working tree.
