It can be since it's a y/n question (remember the "are you sure" types) 
and it's always there unless I answer y. So if I don't want to set the 
global identity, it's always there, in addition to the question for the

I think you misunderstood my proposal. In my proposal there is no 
additional question. It's only the question that is already there right 
now, but if it finds DARCS_EMAIL or ~/.darcs/author it will use the value 
from there as the default. If you keep the default (press enter), nothing 
will get saved in _darcs/prefs/author (since you already have it 
globally), but if you do change it, it gets set per repository. The only 
thing that changes from the current approach, is that if you already have 
a global email set, you can answer that initial question by pressing 
enter. So there is no additional question.

Again, I exposed in my email the dangers of having the global identity if 
you use multiple identities in different projects. My proposal still lets 
you set a global identity, but prevents you from forgetting about it and 
inadvertently using it in a new project that needs another one.
