Bug#13618 : mysqldump --xml omits comment on table field

Browse Source 
When mysqldump tries to dump information in xml format,
the result does not contain field level comments.

In order to retrieve various informations for a field/column,
mysqldump currently uses 'show fields from <tab>' statement.
The attributes returned by the statement lacks the information
regarding field comments.

Fixed by changing the query to one that probes I_S to retrieve
required field informations, including the field comment.
