`squash` discards history of all sub-namespaces #2309

squash new old where new is ahead of old should keep all the old history and just create (at most) a single step for any updated subnamespace.

Instead it appears to discard all history of all subnamespaces of old, leading to really bad LCAs later.

Step 1 is just a transcript to reproduce this.

IIRC this would be a new command. I don't think any special knowledge is needed to implement this, but I'm happy to discuss or review.

Closing this because history for subnamespaces at all is on its way out for now.
