Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

In #3911, a refactor to share `MessageData` code between `ppConst` and the signature pretty printer unintentionally caused the signature pretty printer to use the `pp.tagAppFns` option. This causes, for example, `+` in `a + b` to independently have its own hover information due to the fact that `notation` app unexpanders use the head function's syntax as the `ref` when constructing the notation syntax. This behavior of `pp.tagAppFns` is intentional, and it is used by docgen, but it should not be activated for signatures. This affects `#check` and was reported by Kevin Buzzard [on Zulip](https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/degraded.20hover.20experience.20on.20.23check/near/449380674). This PR also makes sure the initial `ref` when applying app unexpanders is `.missing`, rather than whatever random value might be present in the `CoreM` context. |
