Re: [gentoo-portage-dev] [PATCH] Ignore blockers when fetching and using --ask

[Jason Stubbs <jstubbs@gentoo.org>]

While not harmful, there was one issue with the previous patch; the parent of 
the blocking package would be fetched as well. This would usually mean that 
one of the packages being merged would be fetched twice. This patch fixes 
that.
