Subject: Discard "nomerge" nodes to speed up depgraph.altlist() since those nodes aren't used... 
X-Git-Tag: v2.1.3~127
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=864a6ef93103956c0bd9a3f12aeaf84bc86f391d;p=portage.git

Discard "nomerge" nodes to speed up depgraph.altlist() since those nodes aren't used and the --tree algorithm does a good job of regenerating them when appropriate. (trunk r7067)
