Merge branch 'ab/rebase-no-reschedule-failed-exec'

"git rebase --[no-]reschedule-failed-exec" did not work well with
its configuration variable, which has been corrected.

* ab/rebase-no-reschedule-failed-exec:
  rebase: don't override --no-reschedule-failed-exec with config
  rebase tests: camel-case rebase.rescheduleFailedExec consistently

 --no-reschedule-failed-exec::
 	Automatically reschedule `exec` commands that failed. This only makes
 	sense in interactive mode (or when an `--exec` option was provided).

+Even though this option applies once a rebase is started, it's set for
+the whole rebase at the start based on either the
+`rebase.rescheduleFailedExec` configuration (see linkgit:git-config[1]
+or "CONFIGURATION" below) or whether this option is
+provided. Otherwise an explicit `--no-reschedule-failed-exec` at the
+start would be overridden by the presence of
+`rebase.rescheduleFailedExec=true` configuration.
