Re: [PATCH v4 0/8] Allow relative worktree linking to be configured by the user

> This series introduces the `--[no-]relative-paths` CLI option for
> `git worktree {add, move, repair}` commands, as well as the
> `worktree.useRelativePaths` configuration setting. When enabled,
> these options allow worktrees to be linked using relative paths,
> enhancing portability across environments where absolute paths
> may differ (e.g., containerized setups, shared network drives).
> Git still creates absolute paths by default, but these options allow
> users to opt-in to relative paths if desired.
> 
> Using the `--relative-paths` option with `worktree {move, repair}`
> will convert absolute paths to relative ones, while `--no-relative-paths`
> does the reverse. For cases where users want consistency in path handling,
> the config option `worktree.useRelativePaths` provides a persistent setting.
> 
> A new extension, `relativeWorktrees`, is added to indicate that at least
> one worktree in the repository has been linked with relative paths. This
> extension is automatically set when a worktree is created or repaired
> using the `--relative-paths` option, or when the
> `worktree.useRelativePaths` config is set to `true`.
> 
> The `relativeWorktrees` extension ensures older Git versions do not
> attempt to automatically prune worktrees with relative paths, as they
> would not not recognize the paths as being valid.

> - Split patches into smaller edits.
> - Moved tests into the patches with the relevant code changes.
> - Removed global `use_relative_paths` and instead pass parameter to functions.
> - Changed `infer_backlink` return type from `int` to `ssize_t`.

> - Reordered patches
> - Link to v2: https://lore.kernel.org/r/20241028-wt_relative_options-v2-0-33a5021bd7bb@pm.me
> Changes in v2:
> - Fixed a bug where repositories with valid extensions would be downgraded
>    to v0 during reinitialization, causing future operations to fail.
> - Split patch [1/2] into three separate patches.
> - Updated cover letter and commit messages.
> - Updated documentation wording.
