The migration in #170 collapsed every run of blank lines in the 48 files it touched, including inside verbatim copies of upstream code (e.g. curve_curve_p3.cpp), so they no longer diffed cleanly against upstream. Restore exactly those 91 blank lines; nothing else changes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

// difftest shim for unit `nlib.srf_tool_p2`.

// Wraps N_SrfRemoveKnotConditional, N_SrfRemoveOneKnot and N_SrfElevateDegree
|

// (upstream source/SMLib/src/NL_SrfTool.cpp).

|
|
// One entry point, sc_nlib_srf_tool_p2_eval(op, in, n_in, out, cap, out_len): `op`
|
|
// selects the routine, `in` holds its inputs, `out` receives a flat record of
|
|
// doubles: the status (0 = ok, else NL_ERROR.eno, cleared before the call; 1000 if
|
|
// the flag was set without a number), then, on success only, the results.
|
|
//
|
|
// A surface in `in` is: n m p q, then (n+1)*(m+1) control points (x y z w,
|
|
// row-major), n+p+2 u knots, m+q+2 v knots (storage = indices in use). Everything is
|
|
// allocated on one NL_STACKS. The Rust wrapper validates the surface (valid clamped
|
|
// knot vectors, degrees 1..=NL_MAXDEG) and the parameters (finite; knot index,
|
|
// multiplicity and row range of N_SrfRemoveOneKnot inside the arrays) so upstream
|
|
// only touches the storage it allocates.
|
|
//
|
|
// A surface is dumped as n m p q r s, the control points, the u and v knots.
