git bisect start

# Prune commits 1e5b753bf4..806734c1b1 introduced by 0186faf2a1 (Eglot
# merge on Oct 20 2022)
# The following tells Git that all the commits between Eglot's root
# and its merge to master (excluding the merge-commit itself) are
# regarded as "good", so "git bisect" will never descend into the
# Eglot's branch, because that branch doesn't have all the files.
