Format fix 2005/anon/README.md + add alt version

The alt version uses the same code but the make rule is different. It
disables the stty command. This is in case a shell does not support it.
It also allows to demonstrate a funny feature that the author documented
where after too many moves the program deliberately destroys its runtime
stack. This is because the program sometimes deliberately generates
unsolvable puzzles to hook you :-) and also to prevent you spending too
much time or from getting too frustrated (see also the part about
unsolvable puzzles being deliberately generated).

+
+This program sometimes will create unsolvable puzzles :-) just to hook you.
+As a protection against this - and to prevent you from spending too much time on
+such puzzles (or too big puzzles if you insist on doing this) - it deliberately
+destroys its runtime stack. See the [README.md](2005/anon/README.md) for more
+details on this.
+
+If you specify more than three args the program might also crash or do something
+strange. This might also happen if you specify excessively large board
+dimensions. Try `100 100 100` for instance and see what happens!
