 An EQUS can be expanded to a string that contains another EQUS

-This means that, if you aren't careful, you may trap the assembler into an
-infinite loop if there's a circular dependency in the expansions.
+If this creates an infinite loop, RGBASM will error out once a certain depth is reached. See the -r command-line option.
