I think that this function (`set_group_records_option()`), and the one preceding it (`set_live_update_option()`) are redundant and can be removed. Can anyone tell me when they get called?

It seems like they *should* be assigned to a filter around line 31, where `set_screen_option()` is. But they're not.

Further more, I think that these functions are designed to update their respective screen options when the screen options form is submitted. However, they are ajax-ified, so they are already set before the submission. Plus, they don't have an 'Apply' button, like the Records per Page screen option does.

*Also*, if javascript is disabled, the screen options tab doesn't even show, so it's impossible to access these options.
