[PATCH 2/2] t: git-show: adapt tests to fixed 'git show'

[Max Kirillov <max@max630.net>]

'git show' used to print extra newline after merge commit, and it was
recorded so into the test reference data. Now when the behavior is
fixed, the tests should be updated.

Note that '--format=%s' works like '--pretty=tformat:%s'. This
is why non-merging cases pass, like t3505-cherry-pick-empty.sh
for example, though they look very similarly.
