One way [manual, automatable]: given commits 1, 2, 3, 4, 'hide' 2:
bzr branch r 1 source tmp
cd tmp
bzr bzr -r 3 $source; bzr commit -m message-of-three
bzr merge $source; commit -m message-of-four
bzr push $source
A default log of $source will show
message4
message3
orig1
And a verbose (-n0) log:
message4
orig4
message3
orig3
orig2
orig1
Thats the history perserving way.
The history discarding way is:
bzr branch -r 1 $source tmp
cd tmp
bzr merge $source -r 3
bzr revert --forget-merges
bzr commit -m <message of 3>
bzr merge -r 3..4 $source
bzr commit -m <message of 4>
bzr push $source
Which is I think equivalent to what you sketched.
Cheers,
Rob
