Re: file name case-sensitivity issues

On OS X using whatever filesystem it comes with by default, I get the following, which doesn't seem right (but in a different way).

$ mkdir case-sensitivity-test
$ cd case-sensitivity-test
$ git init-db
defaulting to local storage area
$ echo foo > foo
$ echo bar > bar
$ git add foo bar
$ git commit -m initial\ commit

$ git checkout -b side
$ echo bar-side >> bar
$ git commit -m side\ commit -o bar
$ git checkout master
$ rm foo
$ git update-index --remove foo
$ echo FOO > FOO
$ git add FOO
$ git commit -m case\ change
$ ls
FOO bar
$ git pull . side

Nope.

The checkout is losing the FOO file but the merged tree object has the merged FOO in it.
