Description:
The 'myisam_max_extra_sort_file_size' variable is never actually used. It sets the C-level global variable myisam_max_extra_temp_length, but then that value is never used by mi_too_big_key_for_sort().

How to repeat:
This behavior was changed with this changeset:

ChangeSet@1.1354.54.3, 2002-11-28 15:16:56+05:00, wax@mysql.com
  Correct view of sort.c and mi_too_big_key_for_sort()

Suggested fix:
Either restore the usefulness of myisam_max_extra_sort_file_size or remove it from the documentation.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.

I removed the variable from the 5.1 and 6.0 manuals.
In the 5.0 manual it is noted as unused (and removed as of 5.0.6).
I left the 4.1 manual unchanged.
