Bug 2139379

.`git` rebased to version 2.39.1 The `Git` version control system has been updated to version 2.39.1, which provides bug fixes, enhancements, and performance improvements over the previously released version 2.31. Notable enhancements include: * The `git log` command now supports a format placeholder for the `git describe` output: `git log --format=%(describe)` * The `git commit` command now supports the `--fixup<commit>` option which enables you to fix the content of the commit without changing the log message. With this update, you can also use: ** The `--fixup=amend:<commit>` option to change both the message and the content. ** The `--fixup=reword:<commit>` option to update only the commit message. * You can use the new `--reject-shallow` option with the `git clone` command to disable cloning from a shallow repository. * The `git branch` command now supports the `--recurse-submodules` option. * You can now use the `git merge-tree` command to: ** Test if two branches can merge. ** Compute a tree that would result in the merge commit if the branches were merged. * You can use the new `safe.bareRepository` configuration variable to filter out bare repositories.
