[PATCH next] git-notes: add test case for multi-line notes

["Tor Arne Vestbø" <tavestbo@trolltech.com>]

The tests adds a third commit with a multi-line note. The output of
git log -2 is then checked to see if the note lines are wrapped
correctly, and that there's a line separator between the two commits.

Also, changed from using 'git diff' to test expect vs. output to use
'test_cmp', as I had problems getting correct results using the former.
