History: * Back in (pre June) 2018 worktrees in git just worked. * https://dart-review.googlesource.com/c/sdk/+/48091 made it not work. * https://github.com/dart-lang/sdk/issues/33619 was filed. * https://dart-review.googlesource.com/c/sdk/+/127485 was created to work around the problem. I don't know when it happened, but I can't make the above workaround work (at least not anymore) --- adding a `default_git_folder` to my `args.gn` has no effect. This CL builds on it and automatically sets the correct path based on a call to `git rev-parse --resolve-git-dir .git` which gives the correct dir for both worktrees and non-worktrees.
