[PATCH v2 08/10] merge-ort: implement format_commit()

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

This implementation is based on a mixture of print_commit() and
output_commit_title() from merge-recursive.c so that it can be used to
take over both functions.
