Undoing 'sweep-pitch'

Anybody know why ‘Undoing sweep-pitch’ would be in the command line? (It’s not a custom alias FYI - but I noticed it during some displacement I was doing).

Just wondered why it came up, if it was some bug.

I think it’s when undoing displacement changes.

Okay - I see this now in here.
