Description:
According to the manual, http://dev.mysql.com/doc/refman/5.0/en/myisampack.html, myisampack has the following option:

"--packlength=len, -p len

Specify the row length storage size, in bytes. The value should be 1, 2, or 3. myisampack stores all rows with length pointers of 1, 2, or 3 bytes.
..."

This option is not recognized by myisampack in any modern version of MySQL, though.

How to repeat:
openxs@suse:~/dbs/5.0/var/test> ../../bin/myisampack -p 1 tbig.MYI
../../bin/myisampack: unknown option '-p'
openxs@suse:~/dbs/5.0/var/test> ../../bin/myisampack --packlength=1 tbig.MYI
../../bin/myisampack: unknown variable 'packlength=1'
openxs@suse:~/dbs/5.0/var/test> ../../bin/myisampack --version
../../bin/myisampack Ver 1.23 for suse-linux on i686

Suggested fix:
Remove this option from documentation, as it is misleading. Or implement it.

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.

It is a pack_isam option only. Removed it from the 5.0/5.1 manuals and made a note in the 3.23-4.1 manual that it's pack_isam-only.
