(keyword "") can be printed, but not read

Description

user=> (keyword "")
:
user=> (prn-str *1)
":\n"
user=> (read-string *1)
java.lang.RuntimeException: java.lang.Exception: Invalid token: : (NO_SOURCE_FILE:0)

This obviously isn't a huge defect, but I'd argue that anything that can be printed should be readable.

Environment

None

I have cloned this at http://dev.clojure.org/jira/browse/CLJ-2014 as I came up against this problem. It was quite hard to track down.

After a brief review of places that call intern, it appears that this problem might never be reached in the reader, only in user code calling (keyword ...). Does it make more sense to have the patch there, and a matching change for (symbol ...)?

Patch that throws IllegalArgumentException would be ok for this.
