SlotMachine.lua built "%s lined up!\nScored %d coins!" as a plain Lua
literal, substituting the symbol id (sym) as if it were part of the
translatable sentence. The real extracted _LinedUpText label
(" lined up!\nScored {RAM:wStringBuffer} coins!") shows the original
never had a slot for the symbol at all -- it was drawn separately and
only this fixed suffix was ROM text. Concatenate sym in front of
romText's real, already-translated label instead of interpolating it
into an engine literal.
