#8 Only one warning

[Rob Steele]

MySQLdb gets wedged once any query returns an info
message with warnings. Subsequent queries throw the
exception belonging to the query that produced the info
message.

This patch fixes the bug but I think it might be better
if Cursor.messages were changed from an array to a
string and renamed Cursor.message. I don't understand
why you'd want more messsages around than the one from
the latest query--it seems like a memory leak.

For MySQLdb/cursors.py from MySQL-python-0.9.2c1.

MySQLdb rocks!

You're might be right that it's broken, but a bigger problem
is that it's not correctly implementing what's in PEP-249.
I'll rework this for c2. Thanks for the heads-up.
