Git question

[Deron Johnson]

I have created a branch of the xserver git repository and I have done a 
git commit -a of my changes and followed it
with a git push of the branch. But when I pull over a new copy of the 
repository and check out my branch none of my
changes are there. This sequence worked for me when I was creating 
looking glass branches a while back. Does anybody
know why it isn't working now?  (BTW: I am using git 1.4.4).
