Description of problem:
Yum outputs ugly strings like "0 Package(s)".
Please make use of the gettext plural forms feature so that the output is like "1 Package", "2 Packages" ...

Something like the following patch does part of the job, but there are more occurences that are not that straightforward and my Python skills are too poor to rewrite the code properly :-(
