--- This is used when displaying craft recipes, where an ingredient is
--- specified by group rather than as a specific item.  A single-item group
--- is represented by that item, with the single-item status signalled
--- in the "sole" field.  If the group contains no items at all, the item
--- field will be nil.
---
--- Within a multiple-item group, we prefer to use an item that has the
--- same specific name as the group, and if there are more than one of
--- those items we prefer the one registered for the group by a mod.
--- Among equally-preferred items, we just pick the one with the
--- lexicographically earliest name.
---
--- The parameter to this function isn't just a single group name.
--- It may be a comma-separated list of group names.  This is really a
--- "group:..." ingredient specification, minus the "group:" prefix.
