.gitignore polution

Heya,

I usually compile git from next (sometimes pu to test out a new
feature), and when I then switch back to a development branch (usually
based off master) I get something like this:

$ git status
# On branch remote-helpers
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#	git-http-backend
#	git-notes
#	git-remote-hg
#	test-index-version

Now I can easily do 'git clean -f', but it's somewhat annoying. How do
other developers deal with this?
