You are right. I had experimented with only one package and the 
behaviour was as I said, but on doing "yum list|less" I see that some 
packages are indeed reported on two lines. Yum is clearly formatting
the output with a default maximum line length (or screen width), even 
though I did this on a wide terminal window.

So it *is* a bug. This is just not reasonable behaviour, and furthermore 
is at odds with many other Linux tools which either a) notice when 
stdout is not a terminal, or b) have a command-line option to prevent 
this kind of thing.
