Re: [PATCH v4 0/2] includeIf: add "worktree" condition for matching working tree path

> The `includeIf` mechanism already supports matching on the `.git`
> directory path (`gitdir`) and the currently checked out branch
> (`onbranch`).  But in multi-worktree setups the `.git` directory of a
> linked worktree points into the main repository's `.git/worktrees/`
> area, which makes `gitdir` patterns cumbersome when one wants to
> include config based on the working tree's checkout path instead.
