It certainly isn't what will happen on posix systems as there we just ignore it. Maybe nobody knows, which is why nobody sets it? I think it would be best to be consistent with posix systems, and ignore it here too (at least until we have a good reason to do otherwise).
I've always disliked this argument and hoped that someday someone would remove it entirely. My recollection (which may be wrong) is that the only actual use of it is so that if someone types a command, and we later need to print the command back, we will print it with the same quote char. It almost seems like we could just delete the argument and use a standardized quote char when flattening a command string.
