A table lists the values for the new concurrent_insert NEVER, AUTO & ALWAYS new syntax.
However, the table lists AUTO twice:

AUTO (or 1) 	(Default) Enables concurrent insert for MyISAM  tables that do not have holes

AUTO (or 2) 	Enables concurrent inserts for all MyISAM tables, even those that have holes. For a table with a hole, new rows are inserted at the end of the table if it is in use by another thread. Otherwise, MySQL acquires a normal write lock and inserts the row into the hole.

How to repeat:

Suggested fix:
Fix docs to list ALWAYS.
