commit: simplify building parents list
Push pptr down into the FROM_MERGE branch of the if/else statement,
where it's actually used, and call commit_list_append() for appending
elements instead of playing tricks with commit_list_insert(). Call
copy_commit_list() in the amend branch instead of open-coding it. Don't
bother setting pptr in the final branch as it's not used thereafter.
