Bug #13926 mysqldump --order-by-primary fails if PK column needs quoting

Description:
If a tables PK contains a column that needs quoting in SQL (i.e. column name contains whitespace or "/") then 'mysqldump --order-by-primary ...' creates invalid SQL and fails.

How to repeat:
ls3235:~ # mysqltest test
CREATE TABLE t1(`a/b` INT PRIMARY KEY);
--exec mysqldump  --order-by-primary test t1
mysqldump: mysqldump: Couldn't execute 'SELECT /*!40001 SQL_NO_CACHE */ * FROM `t1` ORDER BY a/b': Unknown column 'a' in 'order clause' (1054)
mysqldump: Got error: 1054: Unknown column 'a' in 'order clause' when retrieving data from server
mysqltest: At line 2: command "mysqldump  --order-by-primary test t1" failed

Suggested fix:
Quote PK columns in SQL generated by mysqldump.

Tested an updated patch supplied by Axel, added test and test results to mysqldump test file.

Patch looks okay to me, except for some cosmetic problems pointed out via email.
