You could put a dummy character at the beginning of the string ...

My suggestion:

    local function qfind( s )
      local ok, a, b = string.match( " "..s, "[^\\](\\*)%1()[\"']()" )
      if ok then
        return a-1, b-1
      end
      return nil
    end

(But if you write an extra function for matching, you could as well try 
the two different patterns and save the temporary string ...)
