Description of problem:

When rawhide is increadibly broken just before a test release yum needs long
lists of --excludes to update it.

When I write them late in the evening I always end up with many typoes in one or
more excludes.

For people with exclude-spelling defficiency like me a -x shorthand would be great

Version-Release number of selected component (if applicable):

yum-2.9.3-1

Paul Nasrat suggests the following patch:
