When we start picking a range of revisions we save the replay options that are required to restore state when interrupting and later continuing picking the revisions. However, we do not check the return values of the `git_config_set` functions, which may lead us to store incomplete information. As this may lead us to fail when trying to continue the sequence this error can be fatal.
Fix this by dying immediately when we are unable to write back any replay option.
