This patch 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).
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 helper function, `write_worktree_linking_files()`, centralizes
the logic for computing and writing either relative or absolute
paths, based on the provided configuration. This function accepts
`strbuf` pointers to both the worktree’s `.git` link and the
repository’s `gitdir`, and then writes the appropriate path to each.
In response to reviewer feedback from the initial patch series[1],
this revision includes slight refactoring for improved
maintainability and clarity in the code base.
