Hi Anders,
looks good, just one suggestion, see inlined.

We might want to make sure that `worktree` and `worktree->path` are
non-`NULL`, and otherwise call a `BUG()`.

Okay, I lied, I have two suggestions. Shouldn't this be turned into
`worktree->is_bare`?
Of course, `find_shared_symref()` will currently not return any worktree
with non-zero `is_bare`...

Makes sense. If `worktree` is `NULL`, `do_update_worktree` won't ever be
set, and if `worktree` is not `NULL`, even before we remove that
`is_bare_repository()` ternary, it is set to `find_shared_symref("HEAD",
name)` (and `name` is not changed in the `update()` function).
Thanks,
