Change a list's name, filters or email digest; the fields left out keep their value.
Takes the same fields as a creation, and changes only
those sent; numbers and job_id are ignored here, so add numbers with
add watches. A field left out keeps its value, so none is
required, whatever the contract's request body below marks as required. include_kinds,
exclude_kinds and digest_recipients are replaced whole, not merged. Answers 200 with
the list as it now is.
Turning the digest on starts it from that moment: the first digest holds what the list
matches from then on, not what it matched before. Changing the filters applies to the
events matched from then on; events already delivered stay delivered.
Refused with 400 invalid_request on the same grounds as a creation, and 404 not_found
for a list that is not your organization's. Not counted as a call.
