I tried to reproduce this problem, but couldn't.

This fails because git-add refuses to mark an ignored file as tracked.
So in your altered test above the COPYING file is never tracked.
git-reset then does the proper thing and refuses to remove it.  So it's
still not demonstrating the case you mention below.

Strange.. this little test shows that tracked files that are ignored
do get removed when resetting --hard...

$ mkdir tryit ; cd tryit
$ git init-db
defaulting to local storage area

$ touch one ; git add one
$ git commit -a -m"Initial"
Committing initial tree 5fcffbd6e4c5c5b8d81f5e9314b20e338e3ffff5

$ touch .gitignore
$ git add .gitignore
$ git commit -a -m"now we have gitignore"

$ echo '.*' >> .gitignore
$ git commit -a -m'now git ignores all .* files'

$ ls -l .gitignore
-rw-r--r-- 1 sean sean 3 Jun  2 06:01 .gitignore

$ git reset --hard master~2
$ ls -l .gitignore
ls: .gitignore: No such file or directory
