gitk --all on fedora kexec-tools tree

Hi Chao, I am running "gitk --all" on fedora kexec-tools tree. I kind of expected that master branch runs first and then rest of the branches fork off that. Something like as follows. -------------------------------------------------------> master | | | |--->f18 |----->f19 |---->f20 In my gitk view f20 seems to be on top and it looks as if master has been forked off the main trunk. I am not sure if this is gitk behavior and it is possible that it can show branches anyway, or it has something to do with we fork off branches. Anyway, this is not something very important. I noticed something and thought of bringing it to your notice. Thanks Vivek
