[PATCH 2/2] DONTAPPLY: -Os fallout workaround

[Junio C Hamano <gitster@pobox.com>]

These "workarounds" are to mark variables that are used after
initialized, but some compilers with lower optimization levels
cannot see and report "used uninitialized".

This set targets "gcc-13 -Os".  For the reason why this is a wrong
thing to do for longer-term code health, see

  https://lore.kernel.org/git/xmqqed946auc.fsf@gitster.g/
