No, the current behaviour is not a "sensible default" - I've seen it
confuse people, *and* it's wrong from the perspective of what
namespace those strings (the hostname part of the url) come from.
Consider also that doing a merge like this from different repositories
is extraordinarily rare - enough that I'd even suggest that if the
client makes that leap from the comparison it should warn that it's
doing so, because it's probably not what you wanted...

The user should know what he's doing, and if he doesn't he probably doesn't know about the switches either. Sensible defaults have to be chosen, though - probably defaults to keep the behaviour the same as it is now.
