[PATCH v2 0/2] git notes show: handle empty notes gracefully

"git notes show" barks when there is no note to show. This introduces a
test (yes, a test!) and, in a second round, reacts more gracefully to
empty notes and adjust the expected test output accordingly.

Note that in both cases (before/after the patch) the return code is
non-zero: It's 128 in the ungraceful case, 1 when "dieing gracefully",
uhm...

The main achivement in v2 is the correction of typos in the commit
messages and comments, as well as the addition of proper s-o-b (son of
a...) lines.

Additionally, v2 incorporates input from the two J's. We test explicitly
for return code 1 now.
