Bug #499 Last letter of the string returned by USER() is missing

Description:
When I call the function USER(), the last letter of its result string is always cut off.

How to repeat:
# mysql -h localhost -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6 to server version: 4.1.0-alpha-Max

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
