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

This PR stops the `repeat` inference handler from reporting `numRegularExits := 0` for break-less bodies. For break-less `repeat` the loop never terminates normally, so `0` looks more accurate semantically, but the loop expression still has type `m Unit` and the do block's continuation after the loop is what carries that type. Reporting `0` makes the elaborator flag that continuation as dead code, yet there is no way for the user to remove it that is also type correct — unless the enclosing do block's monadic result type happens to be `Unit`. Pinning `numRegularExits` at `1` (matching `for ... in`) eliminates those spurious warnings. |
