Ilya Grigoriev 1cc10783a2 demos: update demos as little as possible to regenerate them
This updates demos to the point where they can run without
warnings. Some of them become less clear, this is addressed
(where I noticed it) in follow-up commits.

Fixes #3209

comment "We are in the octocat/Hello-World repo.
The \"operation log\" shows the operations
so far:"
run_command "jj op log"
comment "We are going to make some changes to show
how the operation log works. Let's add a file, set
a description, and rebase onto the \"test\" branch:"
run_command "echo stuff > new-file"
run_command "jj describe -m stuff"
run_command "jj rebase -d test"
comment "We are now going to make another change off of
master:"
run_command "jj new master"
run_command "jj describe -m \"other stuff\""
comment "The repo now looks like this:"
run_command "jj log"
comment "The most recent portion of the operation log
is:"
run_command_allow_broken_pipe "jj op log --limit 4"
comment "Let's undo that rebase operation:"
rebase_op=$(jj --color=never op log --no-graph -T 'id.short(5)' --limit 1 --at-op @--)
run_command "jj undo $rebase_op"
comment "Note that only the rebase was undone, and the
subsequent \"other stuff\" change was not undone:"
run_command "jj log"
comment "We can also see what the repo looked like
after the rebase operation:"
run_command "jj --at-op $rebase_op log"
comment "Let's say we instead want to go back to the
state of the repo right after the rebase:"
run_command "jj op restore $rebase_op"
# TODO: Explain and demo that undo and restore are also recorded? Remove demo
# of --at-op?
comment "We're now back to before the \"other stuff\"
change existed:"
run_command "jj log"
