If you examine the implementation of log and graphlog you'll discover
they're basically completely different. The prerequisite for making log
-G a core feature is unifying the implementations.

And that probably means adding a no-graph mode to graphlog that exactly
matches the core log output for all our weird little options without too
many serious performance regressions.
