Currently when automerge starts the engine only records in config.changelog the merge operation but it's not possible to distinguish if they were done manually or by the automerge.

would be nice to:

• record when automerge start/end
• record when automerge is enable/disabled
• be able to distinguish a merge from automerge and a manual automerge
• being able to correlate all merge relative to the same automerge "round"
