Subject: dotgen getCluster: remove unused 'g' parameter
X-Git-Tag: 5.0.1~33^2~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=118c61f7580d1a716a96e98c6f1a4601b30678db;p=graphviz

dotgen getCluster: remove unused 'g' parameter

This also makes `g` in `makeCompoundEdge` unused, so we remove that parameter
too.
