Add a reference for builtin Lua functions, extracting both text and formatting from the Lua 5.1 Reference Manual.
All text referring to implementing Lua into a host C program has largely been removed.
For example:
:help lua_reference_toc
:help math.pi
:help coroutine.yield
Script generated documentation for Lua 5.1 in languages: en, de, es, and pt.
For lazy.nvim:
{
'DrKJeff16/nvim-luaref',
lazy = false,
}
