Looking at what Sergei has proposed upthread again, using a
comma-separated list of options may be more painful for translators as
such lists really depend on the language, so I would be fine to commit
what has been added.

One last point though: we use anti-wraparound in already five places in
the docs, still I have sympathy for "to prevent wraparound" as well.
The brackets look rather useless to me, wouldn't it be better to remove
them? By doing so the longest message becomes:
"automatic aggressive vacuum to prevent wraparound of table blah.blah"
