The original commit a4adced9b5 had its commit message accidentally
polluted with the entire Emacs git log (~15MB). The cherry-pick script
copied this bloat into the new 0002 patch. Regenerated 0002 with a
clean ChangeLog-only commit message (1385 bytes).
B4: Shorten all subject lines to <=50 chars (preference from CONTRIBUTE).
B3: Fix intermediate BUF_CHARS_MODIFF state in 0002: use BUF_MODIFF
from the start, eliminating the wrong-then-corrected pattern across
patches 0002+0007.
B2: Wrap long NEWS line in Zoom entry (was 80 chars, now <=79).
B1: Long block_input comment already fixed by 0004 in both branches;
confirmed no change needed in final state.
N1: Fix DEFVAR doc in 0001 to reflect auto-detection at startup.
N3: Convert VoiceOver NEWS bullet list to prose paragraphs.
N2: Skip (existing file uses 80-char separators throughout; changing
only new ones would be inconsistent).
