t0012: test "-h" with builtins
Since commit 99caeed05 (Let 'git <command> -h' show usage without a git dir, 2009-11-09), the git wrapper handles "-h" specially, skipping any repository setup but still calling the builtin's cmd_foo() function. This means that every cmd_foo() must be ready to handle this case, but we don't have any systematic tests. This led to "git am -h" being broken for some time without anybody noticing. This patch just tests that "git foo -h" works for every builtin, where we see a 129 exit code (the normal code for our usage() helper), and that the word "usage" appears in the output.
