Subject: graph: extract logic for moving to GRAPH_PRE_COMMIT state
X-Git-Tag: v2.25.0-rc0~132^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ee7abb5ffaaba8c3fc5f89765609f30d638f63f7;p=thirdparty%2Fgit.git

graph: extract logic for moving to GRAPH_PRE_COMMIT state

This computation is repeated in a couple of places and I need to add
another condition to it to implement a further improvement to the graph
rendering, so I'm extracting this into a function.
