This series updates `git history fixup`, `reword`, and `split` to honor `commit.gpgsign` as well as the `-S/--gpg-sign` and `--no-gpg-sign` options.
It adds regression tests that cover configuration-driven signing, command-line overrides, and the handling of replayed descendant commits.
Finally, it updates the history documentation to describe the new signing behavior and available options.

Souma (3):
  builtin/history: sign rewritten commits
  doc: document history signing options
  t345x: cover signed history rewrites
