And then anything that uses __gitdir() would fail.

And how would you figure if it's available, and where it is available?
What if git-completion.bash is distributed on
/usr/share/bash-completion/completions/git? Where would you put
git-prompt.sh so it can be found *and* you would not require
modifications? And what if I want to put the latest version on
~/.git-completion.sh (as the script actually suggests).

There's no way git-prompt.sh can be sourced without modifications to
the script, unless you expect it would always be named
'.git-prompt.sh' and would be on the same directory, which many
distributions would frown upon.
