t7614: avoid hiding git's exit code in a pipe
The exit code of the upstream command in a pipe is ignored, so in git cat-file commit HEAD | sed -e "1,/^\$/d" >actual a crash of "git cat-file" would go unnoticed: the exit code of the pipeline is that of "sed", which happily succeeds on empty input. The test would thus pass even though "git cat-file" failed. Write the output of "git cat-file" to a file first and run "sed" on that file, so that the exit codes of both commands are checked by the &&-chain.
