The last time I spoke to an IP lawyer about this sort of thing (~6 months
back, and he's on holiday so I can't check), the answer was:
* published in 1954, expires 31/12/2004
* published in 1954, republished without changes 1959, expires 31/12/2004
* published in 1954, republished with changes / revisions in 1959, this
corresponds to a new work (as new copyrightable material has been
added), expires 31/12/2009
So I believe that if the publication date includes any mention of
revisions or updates, then the later date applies, but if they don't
mention changes, then it's the original date.
