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.
