Description:
In Chap. "5.12.1. The Error Log" there is no comment on the flag log_warnings nor is somewhere explained which levels of warnings are available (1, >1).

How to repeat:
n.a.

Suggested fix:
IMHO it should be written in this chapter that error log can be influenced by show _warnings and which warning is influenced by which show_warnings level:
0 no warnings only error
1 warnings to
>1 also connection errrors.

on the page documenting connection errors: http://dev.mysql.com/doc/refman/5.0/en/gone-away.html
reference is made of the server settings:
--log-warnings=2, 
quote:
You can get more information about the lost connections by starting mysqld with the --log-warnings=2  option. This logs some of the disconnected errors in the hostname.err file. See Section 5.12.1, “The Error Log”.
end quote.
However, section 5.12.1 referenced above contains no information about log-warnings.   Nor can I find documentation of this setting anywhere in the documentation. 

I verified that the same reference and corresponding omission occurs in the 5.1 documentation as well.
