[PATCH 01/17] rev-list: do not do commit simplification if simplify_history = 0

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This is just a workaround to make my series work. Currently, commit
chain will be simplified if pathspecs are given. That would make
pack-objects generate commit chain with gaps.
