From: Johannes Schindelin <johannes.schindelin@xxxxxx>
A common use case for the `--exec` option is to verify that each commit
in a topic branch compiles cleanly, via `git rebase -x make <base>`.
However, when an `exec` in such a rebase fails, it is not re-scheduled,
which in this instance is not particularly helpful.
Let's offer a flag to reschedule failed `exec` commands.
Based on an idea by Paul Morelle.
