Neither this function nor its callers handle errors, but that is in line
with how the other todo list-munging functions work.
I just say this to document that I read this code, noted this shortcoming,
and think that it is okay to keep it this way for the moment.
There is one more fundamental comment I have, though: we already have a
step that converts the todo list to/from the human readable format (by
collapsing/expanding the commit hashes presented in the list). We could
easily make this conversion a part of that conversion.
Once my `rebase-i-extra` patches get accepted, we will need to rewrite
this in C, as part of sequencer.c, anyway. It will look somewhat like
this:
