Answer 1

If you want to permanently ignore these files, a simple way to add them to .gitignore is:

1. Change to the root of the git tree.
2. git ls-files --others --exclude-standard >> .gitignore

This will enumerate all files inside untracked directories, which may or may not be what you want.

Answer 2

If you have a lot of untracked files, and don't want to "gitignore" all of them, note that, since git 1.8.3 (April, 22d 2013), git status will mention the --untracked-files=no even if you didn't add that option in the first place!

"git status" suggests users to look into using --untracked=no option when it takes too long.
