Change the invocation of the "post-rewrite" hook added in
795160457db (sequencer (rebase -i): run the post-rewrite hook, if
needed, 2017-01-02) to use the new hook API.

This leaves the more complex "post-rewrite" invocation added in
a87a6f3c98e (commit: move post-rewrite code to libgit, 2017-11-17)
here in sequencer.c unconverted. That'll be done in a subsequent
commit.

As a reader I'd find it more helpful to explain why the conversion isn't done here rather than leaving be to run "git show" to figure it out. If you re-roll perhaps we could replace the commit citation with something like

sequencer.c also contains an invocation of the "post-rewrite" hook in run_rewrite_hook() that is not converted as the hook API does not allow us to pass the hook input as a string yet.

Best Wishes
