Error with $this->db->list_fields() when using mysql/mysqli

[eluser]flojon[/eluser]
When I use the db function list_fields on a table with dashes the tablename is not escaped and the query fails.

Code:

$this->db->list_fields('table-with-dashes');

results in the following query:

Code:

SHOW COLUMNS FROM table-with-dashes

which fails.

Expected query:

Code:

SHOW COLUMNS FROM `table-with-dashes`

This happens with CodeIgniter 1.6.3 and using bot mysql and mysqli db drivers.
