Hi guys,

I found that my system running fedora rawhide has a weird thing, for
example, 'rpm -qa|grep -i file|sort' gives:

audiofile-0.2.6-2.1
audiofile-0.2.6-2.2.1
desktop-file-utils-0.10-4
desktop-file-utils-0.10-6.1
file-4.16-5
file-4.16-6.2
file-roller-2.13.90-1
filesystem-2.3.7-1.1
filesystem-2.3.7-1.2.1
libxkbfile-1.0.1-1
libxkbfile-1.0.1-1.2
rootfiles-8.1-1.1
xorg-x11-filesystem-0.99.2-3
xorg-x11-filesystem-7.0-1

Is it this a bug or a new feature of yum? Thanks.
