rebase: introduce --reschedule-failed-exec
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. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
