Git malfunctions on the ports tree

This happened several times to me. I had to revert commits. Now this 
happened again.


When several ports have changes in the tree and one of the ports is 
committed with 'cd <categ>/<name> && git commit .' - other ports 
sometimes also get into the commit.

In the message git shows correct files under 'Changes to be committed:' 
and 'Changes not staged for commit:'.

But the commit actually contains files "not staged for commit".


I wonder if anyone else experienced this problem.
