OK, I understand the difference in behavior between the two maps.  But
why is chunked-seq? incorrect?

user> (take 1 (map #(do (print ".") [%]) (range 100)))
(................................[0])
user> (chunked-seq? (range 100))
false
user> (chunked-seq? (map #(do (print ".") [%]) (range 100)))
false
user> (chunked-seq? (take 1 (map #(do (print ".") [%]) (range 100))))
false

The implementation of chunked-seq? checks to see if the sequence is an
instance of clojure.lang.IChunkedSeq.  That doesn't appear to be
sufficient in the case of map taking one collection.

Also, Chas Emerick stated in another discussion that ranges always
produce chunked seqs, but the value of (chunked-seq? (range 100))
seems to belie that.
