banditburai (inline report.py:36): `# health: allow BLE001 S110 -- boundary` waived
neither rule and reported "allow comment ignored: it needs a reason", although the
reason is there. _ALLOW accepts spaces in the rule list, but apply_allows split it
on commas only, so "BLE001 S110" was looked up as one rule name.
The rule list is now split on commas and whitespace, so `BLE001 S110`,
`BLE001, S110` and `BLE001,S110` all waive both rules. A reason is still required.
