Not zero terminating string to display

[deepcoder]

Hello, thanks for this code! Helping me learn how I2C works on Intel Linux box.

I believe your code does not correctly terminate the character string from the command line in some cases.
Simple fix that seems to handle all cases and still yields correct display:

	//Setup the text  argument that was passed to main. remove null and add some extra spaces.

        for(i = 0; i < (strlen(argv[3])) ; i++){
	        text[i] = argv[3][i];
        }
        for(i = 0; i < 4 ; i++){
                text[strlen(argv[3])+i] = 32;
        }
        // terminate string
        text[strlen(argv[3])+4] = 0;

Realize this is very old code, but still helpful. Again, thx!
