-- This is used extensively in ui/data/(cre|kopt)options as a `name_text_hold_callback`.
-- `ConfigOption` will *never* pass the `unit` argument, though,
-- so if it's unset, we'll try to pull it from `option`'s `name_text_unit` field.
-- This field can be left unset (which is the vast majority of cases),
-- in which case we don't do anything fancy with the value,
-- or it can be set to an explicit unit (e.g., "pt" or "px"),
-- in which case we append the results of a conversion to that unit in the final string.
-- It can also be set to `true`, in which case the unit is pulled from user settings ("dimension_units").
