Bleagh, no time for coding... Anyway, I played with this, and the amount
of (duplicate) code that would be required to check if we're only
dealing with one article, and whether the article is fetched or not,
sort of makes it not quite worth the effort.

Unless we're interested in factoring out the tests in
`gnus-summary-select-article' into a new function like
'gnus-summary-current-article-fetched-p', which could be used in both
places. That might make it easier.
