Subject: tests: don't lose misc "git" exit codes
X-Git-Tag: v2.41.0-rc0~157^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fdc79ecba0f4a3ef885f1409d2db5a1dbabd649;p=thirdparty%2Fgit.git

tests: don't lose misc "git" exit codes

Fix a few miscellaneous cases where:

- We lost the "git" exit code via "git ... | grep"
- Likewise by having a $(git) argument to git itself
- Used "test -z" to check that a command emitted no output, we can use
  "test_must_be_empty" and &&-chaining instead.
