[Yum-devel] [PATCH] yum-utils: repoclosure for single package

[Kedar Sovani]

Check for the repoclosure of a single package.

Usecase: My automation scripts wanted to query the yum repositories for
closure of a single package, instead of spending time on checking the
closure for all packages. (Unsure if this is useful for anyone else.)

Please consider for inclusion.
