From b0f0ecd97924ee775e7f3b29366133448f4f8e15 Mon Sep 17 00:00:00 2001 From: Jon Seymour Date: Sat, 21 Aug 2010 14:48:05 +1000 Subject: [PATCH] detached-stash: work around git rev-parse failure to detect bad log refs This commit is required because git rev-parse in 1.7.2 does not correctly indicate invalid log references using a non-zero status code. We use a proxy for the condition (non-empty error output) as a substitute. This commit can be reverted when, and if, rev-parse is fixed to indicate invalid log references with a status code.
