FileStatusListener reacts only onSave

Do you implement `FileStatusListener#fileStatusChanged(VirtualFile)` method as well?
It should be fired when Document is modified, without waiting for changes to be saved on disk.

Note that FileStatusManager indicates _color_ of a file, which is not necessary directly related to its VCS status.

I figured out that under Linux the VirtualFile-FileStatusListener-Event is never fired. Under Windows both Listener works as expected.

So it depends on the OS :-(

It does not.
