Method from_git_diff

devx-pre-commit/src/lib.rs:99–116

Creates the git pre-commit context acquiring the staged files via running `git diff` in `project_root`. The `project_root` is expected to contain the `.git` dir (see [`locate_project_root`] function for more on that). The staged files are stored in [`PreCommitContext`] as paths relative to `project_root`.

    /// to `project_root`.
