It is a terrible UI, because it was not that obvious to me. And I consider 
myself not a git newbie.

Besides, it is not really a temporary branch. If it was, the pull would 
_not_ download all these objects again, would it?

Because I am a Jar-HEAD?

I was _not_ suggesting a long-term branch. Just a way to do-what-i-want 
and not waste bandwidth.

Guess three times why I did not post the patches.

But the real problem is not necessarily the behaviour; it is the obscure 
fashion of the behaviour. You may not understand that problem, because you 
were there from the beginning. You saw the big-bang and how all the 
quarks formed all of a sudden, and how matter and eventually planets 
and suns came into being.

But others (me included) were not there. Or they did not really watch. And 
now they see all these creatures, and plants, and bacteria, and they do 
not understand how these are all connected, because of that. And now they 
think "wow that must have been some intelligent design, and really a 
miracle, and I cannot understand how it works." But that is not true 
(the latter part of course).

There is something to be said about the simplicity of Mercurial. It's 
inner workings may suck, but people get easily attracted by it.

I do not claim we should imitate Mercurial, or even hide the index (even 
if I sometimes wonder if the index is not just a clever way to accelerate 
commits, and nothing more).

But the interfaces should be usable interfaces! They should _explain_ what 
they do. Other software does so, it can't be _that_ hard.

I find that quite easy to understand. Why? Because I happen to _know_ the 
syntax of -merge and -fmt-merge-msg. For similar reasons I _understand_ 
why -pull behaves like it does. But others don't; they will shudder and 
then run.

Maybe it is not important that -pull fetches all objects all over again. 
But it _is_ important to make things like merging branches (local or 
remote) trivial. It _is_ important to make the user experience be fun.

Ciao,
Dscho
