Pretty Printing with --print-value or --value-to-string

[phreed]

Can one of these options be used to pretty-print the repl output?
In particular, can the behavior of whidbey, which uses puget, be obtained by associating puget with either --print-value or --value-to-string?
If so, what would the argument to the option look like?
The documentation for these two options is brief.

Now that nREPL support pprint natively I think it'd be a good idea to just use that instead. I'd make the pprint the default, as I guess most users would consider this better UX.
