#clean_column_value(v) ⇒ Object
There are two basic ways to clean a column’s value: h() and sanitize(). The latter is useful when the column contains valid html data, and you want to just disable any scripting. People can always use field overrides to clean data one way or the other, but having this override lets people decide which way it should happen by default.
Why is it not a configuration option? Because it seems like a somewhat rare request. But it could eventually be an option in config.list (and config.show, I guess).
