Thank you for the support!

None of these. I even do not remember sharp command how I fall into this. This were two or three months ago... I just remember that I have added this file to "ignore" it from tracking:
git update-index --assume-unchanged lib/Mojo/IOLoop/Stream.pm
This feature is like: hide file from output. Git do something with this file so it is tracked in some way but just is not displayed when `git status` command is done.
So it would be nice if I can do:
git hide lib/Mojo/IOLoop/Stream.pm
and this file is hidden from output. But `git status --verbose` will show it anyway. Compare:
git status

5 lib/Mojo/IOLoop/Stream.pmI am not expert, this is just my user point of view. Probably there alredy some exisisting interface. I just outline how it would be handy from my point.
Also this topic seems hot: https://stackoverflow.com/questions/936249/how-to-stop-tracking-and-ignore-changes-to-a-file-in-git
