Minor inconsistency in 'some docstring

[Daniel Werner]

(doc some) says:

"... this will return true if :fred is in the sequence, otherwise nil:
(some #{:fred} coll)"

However, some returns the matching value instead:

=> (some #{:fred} [:foo :fred :ethel])
:fred

Attached patch fixes the docstring. (Not that applying the patch would
be any easier than fixing it by hand :-)
