Swapped " - " for a semicolon where it joined two independent clauses,
or a comma where the following text was an appositive/dependent phrase
with no subject of its own. Markdown-style list bullets in
tests/live_test.sh's header (leading "- Item") are unaffected - those
are structural, not sentence punctuation.
Also dropped a "Spec §5.4:" citation in edit.rs missed by the earlier
spec-citation cleanup (case-sensitive grep at the time didn't match the
capitalized "Spec").
