Btw, this is most definitely not a documented thing and requires a bit
of core git knowledge, so perhaps the "shell-scripts were good for
hackers to learn what to pipe where" really *is* a very important point.
Agreed.
Still, it is very impressive, it is supported (and will be
supported, I assume),
and as such - worth mentioning at least in these examples everyone keeps
dreaming about. Until that happened, why not mention that the output
of "git ls-tree" is compatible with --index-info of "update-index"?

I do not like the one that does the whole tree that much. I
would think "git-read-tree -m HEAD" would be simpler and more
efficient if you are reverting the whole tree.
On the other hand, I designed --index-info to be compatible with
ls-tree output (it is not an accident, it was designed). In
git ls-tree HEAD frotz | git update-index --index-info
"frotz" part does not have to be the exact path but can be a
directory name. It means "revert everything in this directory".
This is quite heavy-handed and you would probably want to run
update-index --refresh afterwards.

I would prefer "git update-index --reset frotz" or "git checkout
--index HEAD frotz". git ls-tree|git update-index is too cryptic for
me and too long for my fingers.

Yep, that's what I use... "git-undo-update-index" is
#!/bin/sh
git-read-tree -m -i HEAD
