RememberByUnit fed C_PlayerCache.RememberPlayer from group, target, mouseover and nameplate units. It added nothing the engine's name cache doesn't already learn, and for out-of-range group members it passed a nil class and raised RememberPlayer's usage error.

-- A pfUI library that remembers the level of every player it sees: in the
|
|
-- friends, guild, raid and party rosters, in /who results, and as target,
|
|
-- mouseover or nameplate. The levels are persisted within pfUI_playerDB, for
|
|
-- the places that only have a player's name, such as chat links and offline
|
|
-- friends. Anything with a unit reads the unit itself instead. A player's
|
|
-- class comes from C_PlayerCache.GetPlayerInfoByName, not from here.
