Okay, this one is tricky. The behavior I would want is for
`feature.manycommits` to override the _default_. And if I set
`feature.manycommits = false` (e.g. via `git -c
feature.manycommits=false ...`), I would want the default to "go back".
So I'd really rather see this as
if (!repo_config_get_bool(r, "feature.manycommits", &b) && b) {
rs->core_commit_graph = 1;
rs->gc_write_commit_graph = 1;
}
[...]
repo_config_get_bool(r, "core.commitgraph", &rs->core_commit_graph);
I.e. override the default only if `feature.manyCommits` was true *in the
end*.
In any case, we really need to make sure to handle the `= false` case
correctly here. We might want to override the setting from the
command-line, or it might be set in `~/.gitconfig` and need to be
overridden in a local repository. We need to handle it.
Otherwise this looks good!
