Git stores absolute paths when linking worktrees to the main repository.
However, this can cause problems when moving repositories and worktrees,
or when working in containerized environments where absolute paths
differ between systems. The worktree links break, and users are required
to manually execute `worktree repair` to repair them, leading to workflow
disruptions. Additionally, when repositories are mapped inside containers
with different absolute paths, they may become unusable. Repairing
worktrees in the container can then break them outside the container.
In some cases, relative paths can eliminate the need for `worktree repair`.
If both the repository and worktrees are moved together while preserving
their relative locations, the links remain intact. Common examples include
moving repositories and worktrees or mapping both inside containers that
use different absolute paths.
This patch adds support for optionally _writing_ relative paths to the
linking files. If desired, relative paths can be created through the
`--relative-paths` CLI option for `worktree {add,move,repair}` as well
as the `worktree.useRelativePaths` config option. If an existing
worktree uses absolute paths, executing `worktree {move,repair}` with
the relative option will create relative paths (and visa versa).
A new function, `write_worktree_linking_files()` is introduced to clean
the actual relative path computation in different locations. The
function accepts a strbuf to the worktree `.git` file and a strbuf to
the repository `gitdir` file and then writes the appropriate path to
each as configured by the user.
Additionally, `repair_worktrees_after_gitdir_move()` has been introduced
to address the case where both the `<worktree>/.git` and
`<repo>/worktrees/<id>/gitdir` links are broken after the gitdir is
moved (such as during a re-initialization). This function repairs both
sides of the worktree link using the old gitdir path to reestablish the
correct paths after a move.
