#4385 (ok 4.2.1) Grid edit on sorted columns fails

[Benjam]

When a table is sorted, and an attempt is made to edit a value in the column that is sorted, the query that is generated has the sort order number as part of the column name.

e.g.- for the foo column, it's been sorted 'desc', and so gets an arrow and a sort order number '1' in the column header.
When I try to edit a value in that column, the query that gets created is thus:
UPDATE `db`.`table` SET `foo 1` = '0' WHERE `table`.`id` = 1

Note the space in the column name of the SET clause.
This obviously throws an error and is not what's expected.
