merge doesn't remove files

Hi, please see http://bugs.debian.org/403104

Shouldn't git remove the original file after merging a commit that moved
the file away?  Here's a simple test case:

$ mkdir repo && cd repo
$ git init-db
defaulting to local storage area
$ echo a >foo && git add foo
$ git commit -a -m'add foo'
Committing initial tree 86de5e13286a8449a8a706a58e63be6781770b12
$ git branch b  
$ git mv foo bar
$ git commit -a -m'move foo'
$ git checkout b
$ echo ttt >>foo
$ git commit -a -m'change foo'
$ git pull . master
Trying really trivial in-index merge...
fatal: Merge requires file-level merging
Nope.

$ git status

nothing to commit
$ ls

Thanks, Gerrit.
