[sugar] adding versions to journal/datastore

[Christopher Sawtell]

I am new around here & did not realise that the list server doesn't
munge the addresses, my apologies.

Anyway, I responded to Mikus thus:-

I agree the 'effort' is theoretically trivial, what "versioning"
provides is a new version number without the need to _remember_ that
one has to create a new file name for the new version, and that, for
many people, is far from trivial.

Remember that in times of yore - pre 1981 - versioning was a standard
feature offered by many O/Ss.

These days the need for versioning has become somewhat nebulous
because the various source code control systems allow one to check in
and out, and to see the differences very simply.

Whether or not children should have to deal with that level of
complexity in order to be able to 'undo' the latest, & erroneous,
changes to their current 'magnum opus' is, I suppose, open to debate.
