Function color is inconsistent in syntax highlighting

[AdamCanady]

Example: https://github.com/cockroachdb/cockroach/blob/master/pkg/server/server.go#L406-L414

ClusterID is purple and AnnotateCtxWithSpan is orange. The only difference I can tell is that this occurs when there are multiple returned items (itemOne, itemTwo) vs just one uuid.UUID
