Several godoc comments led with a stale or incorrect identifier, left over from renames, exported/unexported changes, copy-paste between sibling declarations, or plain typos. As a result the documented name no longer matched the function, method, type, or var it describes. Correct each leading word to the name of the declaration it documents.
