title: How to commit changes inside a submodule in Eclipse's eGit?
body: <p>So Eclipse's git plugin - eGit - has been supporting submodules for a while now (they added support in 1.3 release on February 15, 2012, so over a year now). I've just started to use them. I am able to add a submodule without a problem, I can create and checkout a branch inside the submodule for my local patches. I can also create a commit in the submodule.</p>
  
  <p>But how do I update master repository with the pointer to the new commit? When I choose "Update submodule" it rather reverts me back to the original commit that was checked out upon adding the submodule (which isn't surprising when you think what <code>git submodule update</code> does). When I hit "Sync submodule" it doesn't appear to do anything at all.</p>
  
  <p>So is there a way to make the master repo aware of the new commits in the submodule using eGit? I know perfectly well how to do that from the command line, but still I am trying to find out if that is possible from eGit.</p>
