Metalua is a substantial enhancement to Lua. It deserves documentation that is easily digestable. People like me tend to be irritated by typos, which might slow down casual readers. No changes to any code, only the documentation is considered. The changes are in a separate branch "spott-fixspelling" tracking "origin/master".
