Subject: t6200-fmt-merge-msg: Exercise 'merge.log' to configure shortlog length
X-Git-Tag: v1.7.4-rc0~207^2~1

t6200-fmt-merge-msg: Exercise 'merge.log' to configure shortlog length

Add a test to exercise the 'merge.log' configuration option of 'git
fmt-merge-msg'. It controls the number of shortlog entries to display
in merge commit messages.
