Description:
If I change character set mapping with SET CHARACTER SET character set name,
I can't change it to DEFAULT (ie. disable mapping) with SET CHARACTER SET
DEFAULT.

How to repeat:
1) Install MySQL from binary distribution.
2) Look at "SHOW VARIABLES", variable "convert_character_set" is empty.
3) Execute "SET CHARACTER SET cp1251_koi8"
4) Look at "SHOW VARIABLES", variable "convert_character_set" is "cp1251_koi8". This is OK.
5) Execute "SET CHARACTER SET DEFAULT"
6) Look at "SHOW VARIABLES", variable "convert_character_set" is "cp1251_koi8". It should be empty like in point 2.

Suggested fix:
Sorry, dunno.

I tested it on FreeBSD 4.x and Windows XP. Same bug was in 4.0.12 and I didn't tested earlier 4.0.x versions. In 3.23.x character mapping can be disabled with SET CHARACTER SET DEFAULT without any problem.
