Given that both Junio and I had the same basic question, you'll
probably want to put dependency information into your cover letters.
If a series applies on master, then this isn't needed.  But if it
requires other changes that are in a topic in next or pu, you can name
the topic that it depends upon (e.g. ag/rebase-p, as from the "What's
cooking" emails or you can grab them as branchnames from
git://github.com/gitster/git).  If the dependency is something that
Junio hasn't picked up yet, provide a link to the other submission.

Others may have additional suggestions here...

It comes from my conversion of append_todo_help()[0], on which this
series is based.

Sorry, but where does "write_edit_todo = 0" in the preimage come from?


[GSoC][PATCH v2 2/2] rebase--interactive: rewrite the edit-todo functionality in C

2018-06-13 Thread Alban Gruin
This rewrites the edit-todo functionality from shell to C.

To achieve that, a new command mode, `edit-todo`, is added, and the
`write-edit-todo` flag is removed, as the shell script does not need to
write the edit todo help message to the todo list anymore.

The shell version is then stripped in favour of a call to the helper.
