some printing improvements 

- don't print shared references to cprims, and estimate their
  size better. previously you could get output like this:

```
(#0=#\a
 #0#)
```

Now it looks like:

```
(#\a #\a)
```

- print `#\ ` and `#\newline` instead of `#\space` and `#\linefeed`.
  these seem to be more standard.
