You would want your "git add ." to be safe in dirty working trees---at least some folks wanted so badly enough that "git add ." pays attention to the ".gitignore" mechanism. But `git commit -a` would not change, even if it won't add cruft with well curated .gitignore files. That will be a terrible backward incompatible change for those who expect it only deals with the files it knows about (including the one that is not yet tracked but its presence is known via "git add -N").
