Comment 4 for bug 1819540

I think the library setting makes sense here, with the default behavior following the XUL.

The underlying need to me, though, it just making sure the holds that do appear on the clear list can be cleared.

Regardless of if the setting is set to precise or date, holds need to be clearable with the "Clear These Holds" button on the hold shelf AND the Checkin Modifier "Clear Holds Shelf"
