[PATCH 0/5] rebase -m: fix --signoff with conflicts

From: Phillip Wood <phillip.wood@dunelm.org.uk>

When rebasing with "--signoff" the commit created by "rebase --continue" after resolving conflicts or editing a commit fails to add the "Signed-off-by:" trailer. This happens because the message from the original commit is reused instead of the one that would have been used if the sequencer had not stopped for the user interaction. This series fixes that by introducing an strbuf to hold the message which we then write to rebase_path_message() when stopping for user interaction.

The patches are structured as follows:

Patches 1–3 add private "struct replay_ctx" to "struct replay_opts" and move the private members from the latter into the former. These changes are largely mechanical.

Patch 4 adds strbuf to "struct replay_ctx" to hold the commit message. This change is also largely mechanical.

Patch 5 fixes the bug by using the changes in patch 4 to write the correct message to disc when stopping for user interaction.

This series is based on a merge of 'maint' and 'pw/t3428-cleanup'. In principle it would be passible to avoid the refactoring in patches 1–3 and add a new member to "struct replay_opts" instead. However the changes in those patches are largely mechanical so should be low-risk and they pave the way for more improvements and bug fixes in the future.
