Might be simpler to say:
Introduce a new "git cherry-pick --continue" command which uses
the information in ".git/sequencer" to continue a cherry-pick that
stopped because of a conflict or other error. It works by dropping
the first instruction from .git/sequencer/todo and performing the
remaining cherry-picks listed there, with options (think "-s" and
"-X") from the initial command listed in .git/sequencer/opts.
So now you can do:
$ git cherry-pick -Xpatience foo..bar
... description conflict in commit moo ...
$ git cherry-pick --continue
error: 'cherry-pick' is not possible because you have unmerged files.
fatal: failed to resume cherry-pick
$ echo resolved >conflictingfile
$ git add conflictingfile && git commit
$ git cherry-pick --continue; # resumes with the commit after "moo"

The -s thing doesn't have much to do with this change. But is it a
bug or not? If it's not a bug, then this is not so much a glitch to
note as an important feature to ensure people don't sign off on a
conflict resolution without thinking about it. (I guess I think it's
a bug. It's hard to decide.)

This would start to fail if the message ever changed from "error" to
"fatal", right? I don't think that's a good thing.

How is $head used?

$_x40 is idiomatic and safer with old seds.

This will break when GETTEXT_POISON is set --- test_i18ngrep
automatically succeeds in that case.
Is "Signed-off-by" meant to be translated anyway? I would use
! grep
if testing that.
By the way, that probably should go in a separate test assertion
("-s is not automatically propagated to resolved conflict") to make
it easier to change the behavior later.
