[Cuis-dev] [FIX] `#(1 2 3) printOn:Transcript` does not work

[Gerald Klix]

Hi all, Hi Juan,

Two weeks ago I discovered, that `<some set> printOn: Transcript`
does not work. This is true for every collection, because
Collection#printElementsOn: uses PossitionableStream's protocol.

I am not quite sure, whether there is requirement for printOn:
to restrict itself to Stream's protocol, because the method's
first implementation is more than 22 years old.
Anyways, I consider it nicer and -- more important -- less
surprising that way and `StdIOWriteStream stdout` has the
same issue without any easy workaround.

Please, find attached a fix for that issue.


HTH and Best Regards,

Gerald
