[PATCH] test the commit.gpgsign config option

[Nicolas Vigier <boklm@mars-attacks.org>]

The tests are checking that :

- when commit.gpgsign is true, "git commit" creates signed commits

- when commit.gpgsign is false, "git commit" creates unsigned commits

- when commit.gpgsign is true, "git commit --no-gpg-sign" creates
  unsigned commits

- when commit.gpgsign is true, "git rebase -f" creates signed commits
