git: pull doesn't work

[dmik]

Final testing shows that git pull is somehow broken in git 2.0.0 (dmik branch). An attempt to pull from any repo gives something like this:

D:>gitttt pull -v
Password for 'https://dmik@bitbucket.org':
From https://bitbucket.org/dmik/test
 = [up to date]      master     -> origin/master
 - not something we can merge7293a3f24e44318563

The last line looks quite bogus. We can't release like that, it needs fixing.
