[PATCH 0/2] contrib/subtree: Add -S/-gpg-sign

This patch adds support for the -S/--gpg-sign option to the git subtree command.

Currently, git subtree creates squash and merge commits without applying GPG signatures, even when commit signing is configured via commit.gpgSign. This causes issues in repositories that require signed commits for policy reasons.

The implementation ensures that -S/--gpg-sign behaves consistently with other Git commands, passing the flag through to git commit-tree and git merge where appropriate.

This change improves compatibility with workflows and repositories that enforce signed commits.

Changes have been made to this patch according to a discussion with Junio C Hamano gitster@pobox.com on my previous patch attempt.
