[luatex] [EXT] Documentation of tex.print

[Jérôme LAURENS]

According to the documentation you pointed out, a unique argument can be either a string or a table, but nothing about a single number

Notice that the undocumented tex.print(<number>n) prints the number n whereas tex.print(<number>n, nil) prints nothing, which is expected despite it may feel "a little" out of bounds...
