I did the same experiment with the same result. What I don't understand
is why this is a problem. If you're piping the output of "yum list" to
something else for further processing, you're getting one line of
output, which is what you want.
This is not true.

For example if I run this command
yum list | grep Network
NetworkManager.i386                1:0.7.0-0.12.svn4326.fc9
NetworkManager-glib.i386           1:0.7.0-0.12.svn4326.fc9
NetworkManager-gnome.i386          1:0.7.0-0.12.svn4326.fc9
NetworkManager-openvpn.i386        1:0.7.0-16.svn4326.fc9
NetworkManager-vpnc.i386           1:0.7.0-0.11.svn4326.fc9
NetworkManager-devel.i386          1:0.7.0-0.12.svn4326.fc9
NetworkManager-glib-devel.i386     1:0.7.0-0.12.svn4326.fc9
NetworkManager-openconnect.i386    0.7.0-4.svn14.fc9   updates-newkey
NetworkManager-pptp.i386           1:0.7.0-0.12.svn4326.fc9
yum-NetworkManager-dispatcher.noarch

the result is not as expected.
For the first 7 row I can't know from which repo is the package.
The row 8 is the only one right
For the last row I can't understand what is the version.

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.
