I think the most straightforward, obvious (and therefore safest)
way is to create a new branch from patch-18, and then apply (replay)
only the desired patches.
tla tag --setup original...patch-18 new--b--v # or baz branch
tla get new--b--v
for i in $(seq 21 24)
do
tla replay original...patch-$i
# tla commit
done
for i in $(seq 26 40)
do
tla replay original...patch-$i
# tla commit
done
Do a tla log-for-merge/commit after each replay
if you want to preserve separate changesets, and
information about what you replayed from.
You could also set-tree-version + other stuff, then
replay --reverse each of 19,20, 25 but it's not clear
to me whether that would result in the exact same
tree, in general.
