Re: [PATCH v2 4/7] worktree: inline `worktree_ref()` into its only caller

> We have `strbuf_worktree_ref()`, which works on a strbuf, and a wrapper
> for it, `worktree_ref()` which returns a string. We even make this
> wrapper available through worktree.h. But it only has a single caller,
> sitting right next to it in worktree.c.

> Just inline the wrapper into its only caller. This means the caller can
> quite naturally reuse a single strbuf. We currently achieve something
> similar by having a static strbuf in the wrapper.
