it even tells you which repo the pkgs came from.

The formatting is not friendly to scripts.  It's OK to introduce
a line break to insure columnar format for a terminal,
but output to a plain file should put all the info for one package
onto just one line.

 $ yum list installed  > yum.out  # redirect stdout to an IF_REG file
 $ more yum.out

Notice the line break between the version "...fc11" and the repo 'updates'.
This makes the info hard to parse using 'read' in bash, for instance.
Also there are mystery repos such as 'installed':
ConsoleKit.x86_64                  0.3.0-8.fc11               installed

yes - screenscraping is a bad idea. If you want to do programmatic things 

there are better and simpler interfaces.
