The expansion of a fake user name would have to go in 
expand_user_path(), a fake variable name would have to be expanded 
elsewhere. Now, Dscho mentions in the cover letter that his patch has 
already seen some field testing ("has been 'in production' for a good 
while"). So, we have gained some confidence that the point where the 
substitution happens, in expand_user_path(), is suitable. Therefore, I 
have slight preference for a fake user.
