[Yum-devel] [PATCH] Optimization for pkgExcluder, if we have no excluders do nothing.

[James Antill]

 This seems like what it'd do anyway, the big differences are:

1. We don't .lower() the elements of pkgtup for each call.

2. We don't store everything we load in the whitelist.

...this nets me a 5-10% improvement ... roughly 2.56 seconds => 2.35
seconds, for check-update.
