Description:
If you put the server into ANSI_QUOTES mode,
SHOW CREATE TABLE quotes names using double
quote (") rather than backticks (`). However,
mysqldump does not follow this consistently.
Identifiers will be quoted in the output with
double quote for CREATE TABLE, but not for
DROP TABLE.  For example:

DROP TABLE IF EXISTS `columns_priv`;
CREATE TABLE "columns_priv" (
  "Host" char(60) binary NOT NULL default '',
  "Db" char(64) binary NOT NULL default '',
  "User" char(16) binary NOT NULL default '',
  "Table_name" char(64) binary NOT NULL default '',
  "Column_name" char(64) binary NOT NULL default '',
  "Timestamp" timestamp NOT NULL,
  "Column_priv" set('Select','Insert','Update','References') NOT NULL default ''
,
  PRIMARY KEY  ("Host","Db","User","Table_name","Column_name")
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT='Column privileges';

How to repeat:
Issue:

SET GLOBAL sql_mode='ANSI_QUOTES';

(or start server with --sql-mode=ANSI_QUOTES)

Then run mysqldump.

Note: in MySQL 4.0, SHOW CREATE TABLE doesn't respect ANSI_QUOTES,
so mysqldump doesn't use double quotes at all when ANSI_QUOTES
is on.

Suggested fix:
I suppose quote_name() in mysqldump.c needs
to know whether or not ANSI_QUOTES is on.
