kill: remove the content of the killed branch from its descendents

[kevgo]

Assuming I have this branch hierarchy:

branch-1
 \
  branch-2
   \
    branch-3

I decided that branch-1 was a bad idea and I want to remove it. If I run git town kill branch-1, it removes branch-1 from the lineage. But branch-2 and branch-3 still contain the changes that branch-1 makes, and shipping branch-2 will also ship the changes from branch-1.

To fix this, git town kill should also revert the changes from branch-1 from the other branches.

Maybe only do this if a switch like --revert is provided.

Up until this is added, what would be the easiest workaround right now?
Currently I do

1. git town switch to branch-1
2. git compress
3. git revert on the commit hash generated
4. git sync --all
5. git kill

I was wondering if there is any easier way which anyone might be using?
