No problem, and thank you for sticking with it!

Here you could swap the order of when you write to 'act' and 'tmp',
and thus make the 'mv' unnecessary, like this:

  git commit [...] >tmp &&
  head -1 act >tmp &&
  [...rest of the test...]

Note also that 'head' (or 'sed' in later tests) can open its input
file on its own, there's no need to redirect its standard input.

This is a recurring pattern in patches 1, 4, 8, and 9.

May I ask you to go one step further in restructuring this and the
following tests? :)  Instead of using 'test' to compare the contents
of the $actual and $expected variables, use 'test_cmp' to compare the
'actual' and 'expected' files, something like:

  git cat-file commit HEAD >tmp &&
  sed -ne "s/Signed-off-by: //p" tmp >actual &&
  git var GIT_COMMITTER_IDENT >tmp &&
  sed -e "s/>.*/>/" >expected &&
  test_cmp expected actual
