This series was started to clear false positive when applying Junio's suggestion to to a series written by Ævar [1]. Despite, we don't have much interest in that direction. I think it's still an improvement with this series, namely, we're able to always check Git's exit status code. A naive: "git grep -l 'git.* | wc -l' t????-* |wc -l" reveals 38 other tests also have that pattern. Those tests could be cleaned up later on Change in v5: - restore (albeit with new name and simplified) test_stdout_line_count - trash files will be written in $(git rev-parse --git-dir)/trash In v4, I dropped the test_line_count_cmd completely. A local to t640{0,2} helper was written instead.
