Found out today that git, bless its heart, has non-symmetric UI. watch:

[badger@Clingman bugzilla]$ git pull
Already up-to-date.

After a bunch of head scratching we finally realized that pull only updates a single branch whereas push attempts to update them all. Horrible UI. Imagine the case where you're sharing dozens of feature branches with other developers. Before you push new work you have to git pull in each of them?
