Thanks for reporting this! I also just ran into it when following
subtree's documentation.
The problem stems from this:
git rev-parse -q --verify "$1^{commit}" >/dev/null ||
die "fatal: '$1' does not refer to a commit"
Here, $1 is the "0a8f4f0^.." part.
I then tried removing the "..", which lets the command run but then I
ended up with an empty result. Not sure why that happens, though.
I've CC'd subtree's author, Avery (as identified in
contrib/subtree/README), and David, who added this check long ago
(commit 10a49587fab).

What did you expect to happen? (Expected behavior)
Example should work as documented.
What happened instead? (Actual behavior)
see above.
What's different between what you expected and what actually happened?
Anything else you want to add:
Recommend a fix of the documentation. Due to lack of experience with
subtree I cannot provide.
Please review the rest of the bug report below.
You can delete any lines you don't wish to share.
