From 3deea89c5feb0dfdfb99ea752f83497d97a3bdd5 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Tue, 16 Feb 2010 11:21:14 +0100 Subject: submodule summary: Don't barf when invoked in an empty repo When invoking "git submodule summary" in an empty repo (which can be indirectly done by setting status.submodulesummary = true), it currently emits an error message (via "git diff-index") since HEAD points to an unborn branch. This patch adds handling of the HEAD-points-to-unborn-branch special case, so that "git submodule summary" no longer emits this error message. The patch also adds a test case that verifies the fix.
