RETURNS previously conflated fish's $status exit code with genuine
stdout/printed output, e.g. rm listing "0/1" as if they were print
values rather than exit codes. Rename RETURNS to EXIT STATUS across
all 83 documented functions, and reintroduce RETURNS as a distinct
label reserved for the 15 functions that actually print to stdout.
Update build-manual.py's ENTRY_HEADS to render Exit Status before
Returns, manualtools.py's SECTIONS constant, and AGENTS.md's label
order and label-usage guidance to match. Add two verify-manual.py
regression tests: EXIT STATUS bodies must never contain stray
stdout/printed language, and Returns: must always render after
Exit Status: when both are present. Regenerate docs/fish-config.md.
Previously list rows (Extra secret, OK codes) split on spaces only, so
'KOPIA, TEST' produced the malformed token 'KOPIA,'. Collapse any run of
commas/whitespace to a single space before splitting, so 'A,B', 'A, B' and
'A B' all yield the same entries.
- C1: sponge_purge_only_on_exit / sponge_allow_previously_successful are 'bool'
rows that write true/false (sponge's convention), not on/off; badge maps
true->ON, false->OFF, unset->DEFAULT
- I1: shorten value-page hint to 49 cols so it fits the 50-wide tier
- M1: set -U -- before the var name guards typed values beginning with a dash
