"--dry-run" vs "--execute"?

[Xof]

Right now, the default behavior if "--dry-run" is omitted is to actually do the merge. By the principle of maximum safety, should the switch instead be "--execute" and if omitted, the script should do a dry run instead?

Apologies for the delayed response. I like the idea. Go ahead to implement if you like / if there's time.
