The two regex waivers are gone: s and S already match helix there

s and S search each line as its own haystack, so ^ and $ hold at every line
and . never takes a newline, which is helix's multi_line regex. The waivers
for the old difference, sel-regex-caret and sel-regex-dot-newline, had gone
stale, and --strict stopped on the first before printing its summary.
