format and tabs

```
huh the cookbook says ~T prints a tab but it definitely doesn't on SBCL at least. 
i always had to do something like (format out "one~Ctwo~Cthree~&" #\Tab #\Tab) to get actual tab literals 

~T is for tabular output, not literal tabs.

That section of the cookbook could use more examples.
(format t "one~,8@Ttwo~,8@Tthree~&")
```
