I just rolled myself a package of perl-IO-Compress, which
obsoletes/provides perl-Compress-Zlib, perl-IO-Compress-Base,
perl-IO-Compress-Zlib, and perl-IO-Compress-Bzip2. The resulting "yum
update" looked like this:

# yum update

So, as intended, yum replaced the 4 old packages with the new one.
However, the pre-transaction prompt only mentioned one of the four
packages that was getting replaced, which I imagine could result in
some surprises in other circumstances. Shouldn't the prompt list *all*
of the packages that are being obsoleted?
