[FLOW3-general] Update FLOW3 over git

[Thomas Fritz]

Hi!

I have cloned FLOW3 like described here:
http://forge.typo3.org/projects/team-forge/wiki/Cloning_the_FLOW3_Base_Distribution

When i want to pull the latest changes in my branch i did a 'git pull' and a
'git submodule foreach "git pull"'. I get the following error:
<code>
$ git pull;git submodule foreach 'git pull';
Already up-to-date.
Entering 'Packages/Framework/DocumentationBrowser'
You are not currently on a branch, so I cannot use any
'branch.<branchname>.merge' in your configuration file.
Please specify which remote branch you want to use on the command
line and try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.
Stopping at 'Packages/Framework/DocumentationBrowser'; script returned
non-zero status.
</code>

Kind regards
