After re-reading the code that parses the command line options given to "am" and the previous invocation state we read from $dotest/*, however, I think the way this change uses $keep makes things somewhat inconsistent and harder to follow. Currently the variables are given abstract meaning (e.g. "are we told to record to utf8? yes or no") when we parse our command line options and read from the previous invocation state, and then based on that abstract meaning, a later code decides what exact option we throw at the git commands we invoke (e.g. "utf8=t" -> "-u"). How about doing something like this instead at least for now? It might be better to decide when we parse our options and $dotest/* immediately what options we give to the git commands we run (which your patch does but only to $keep option), but that kind of change (1) belongs to a separate topic and should be done consistently to all options, and (2) I am not convinced if it is necessarily a good change.
Yes, at second glance it's probably better to remain consistent. I didn't like it at first because it's layering complexity on it, but you are right, the existing code follows the same pattern.
