That's it, I've installed it now.

Thanks.

This worked. And as you've mentioned, I lost the uncommitted changes.

Well, I was trying to understand git a bit better, so I started reading the source code and just found that -D wasn't documented on my system, even after a

git clone rsync://git.kernel.org/pub/scm/git/git.git/ GIT_HEAD

I'm talking about following excerpt which I've looked at for 2 minutes:

#!/bin/sh

USAGE='[-d <branch>] | [[-f] <branch> [start-point]]' LONG_USAGE='If no arguments, show available branches and mark current branch with a star. If one argument, create a new branch <branchname> based off of current HEAD. If two arguments, create a new branch <branchname> based off of <start-point>.'

SUBDIRECTORY_OK='Yes' . git-sh-setup

headref=$(git-symbolic-ref HEAD | sed -e 's|^refs/heads/||')

delete_branch () {
     option="$1"
     shift
     for branch_name
     do
         case ",$headref," in
         ",$branch_name,")
             die "Cannot delete the branch you are on." ;;
         ,,)
             die "What branch are you on anyway?" ;;
         esac
         branch=$(cat "$GIT_DIR/refs/heads/$branch_name") &&
             branch=$(git-rev-parse --verify "$branch^0") ||
                 die "Seriously, what branch are you talking about?"
         case "$option" in
         -D)
             ;;
[...]

This is slightly confusing, since I didn't see the shift after delete_branch so it looked like a noop. On top of that "-D" did/does not seem to be documented. Skimming over your patch you've sent later to this list, it appears you've fixed the documentation.
