bpo-29521 Fix two minor documentation build warnings (#41) by Mariatta · Pull Request #84 · python/cpython

Mariatta

Much of bpo-29521 was fixed in parallel with commit
e7ffb99 .  This cleans up the rest.

Apply parallel change to Doc/make.bat to read
"set SPHINXOPTS=-D latex_elements.papersize="
I don't have a Windows system on which to observe the warning,
but it should be necessary.

The warning:

.../workspace/cpython_github/Doc/faq/windows.rst:303:
    WARNING: unknown option: -t

In the Windows FAQ, `How do I keep editors from inserting tabs
into my Python source?`, contained a reference to a Python -t
option. In Python 2.x, this caused Python to issue warnings
about lines with mixed spaces and tabs, but as of Python 3.6
it does nothing.

Per discussion at http://bugs.python.org/issue29387, take
their wording. Python [3] raises an IndentationError or
TabError. Tabnanny is now a module.

…DETECTED

Per supervisor [chat L2376] task assignment + testkeeper L2382 execution
+ theologian L2371+L2378 prediction validated. Empirically confirms
void*-typedef drift class IS REAL — W25b promotion required for full
coverage.

EMPIRICAL RESULT (testkeeper executed):
  Mutation: hir_c_insert_before 2nd arg HirInstr → struct HirBasicBlock*
    in BOTH hir_c_api.h:744 + hir_c_api.cpp:2349 (NO arity change).
  Build cmd: scripts/build_phoenix.sh
  HEAD: dac46b9 (post-W25 Step C lint gate)
  BUILD_EXIT=0 ← DRIFT UNDETECTED at compile time

  ZERO compile errors related to hir_c_insert_before. All 6 §1b callers
  (licm_c.c x1, pass_output_type_c.c x3, simplify_c.c x2) compiled
  silently — caller's HirInstr (= void*) implicitly converted to
  struct HirBasicBlock* per C99 §6.3.2.3 with NO diagnostic.

INTERPRETATION per spec §5 + theologian L2371:
  BUILD_EXIT=0 (uncaught) → void*-typedef drift REAL → W25b promotion
    (HirInstr/HirRegister/HirFunction void* → struct ptr) REQUIRED for
    full drift surface coverage.

CUMULATIVE §5.3 PICTURE:
  ARITY mutation (push 67 baseline + push 76 PASS): closed by Step B + C
    canonical includes. Caught at compile (BUILD_EXIT=2 = good).
  TYPE-ONLY mutation on void*-aliased handles (THIS): UNCAUGHT.
    C99 implicit void*↔struct-ptr conversion masks the drift.

W25 OUTCOME:
  ARITY drift on canonical-included paths: CLOSED (Step B + C, push 75 + 77b)
  TYPE-ONLY drift on void*-aliased handles: OPEN — W25b required

CHANGES: appended POST-STEP-B-FINAL section to
docs/w25-step-b-mutation-baseline.txt (PRE-STEP-B in push 67
911e173; POST-STEP-B arity in push 76 74bf7fc; POST-STEP-B-FINAL
type-only HERE).

Per pythia python#84 framing precision + supervisor L2376: 'arity-drift
surface closed; void*-typedef drift OPEN per push 78 type-only result'.
W25b decision now front-of-queue before INVOKE_* Phase 2.

testkeeper STRICT verify N/A for docs-only commit. Light-scrutiny
gatekeeper APPROVE expected.

AUTHORSHIP: testkeeper executed §5.3 type-only procedure (chat L2382);
generalist commits artifact per role boundary (push 67 + 76 precedent).

Authorization chain:
  - W25 spec §5 + §7 caveat: theologian L2017 + L2329 (3) + L2334
  - TYPE-ONLY mutation choice + endorsement: testkeeper L2380 + theologian L2378
  - Push 78 sequencing: supervisor L2376
