merge: Support --json and --json-error-messages and --json-progress
Seems unlikely to be very useful, but trivial.
And, this completes the story that git-annex sync does not need json,
since every sub-operation is available in a command that does support json.
(Well, except for committing, but that's not a git-annex command.)
