You are merging in the wrong direction. You want to merge git-gui into git.git:

	git clone git://repo.or.cz/alt-git.git mygit
	cd mygit
	git pull -s subtree git://repo.or.cz/git-gui.git master

So you are pulling git-gui into git, not the reverse. But yes, when this happens the entire history of the pulled project (in the above case git-gui) suddenly appears in the history of the parent project (in this case git). If you don't want this to happen then you need to make git-gui into a submodule. That has been talked about being done, but hasn't happened yet in the main git repository. git-gui is currently still being subtree merged in.
