Subject: [GSoC PATCH v5 4/6] t7700: test for promisor file content after repack
Message-ID: <f631993c89586a87d7e5f08ca4df1502d5228464.1775861047.git.lorenzo.pegorari2002@gmail.com>
In-Reply-To: <cover.1775861047.git.lorenzo.pegorari2002@gmail.com>

Add tests that check if the content of ".promisor" files are correctly
copied inside the ".promisor" files created by a repack.

The `-f` flag is used when repacking to ensure that all the packs
(created with `test_commit_bulk`) are repacked into a single new pack.
