Misleading, if not incorrect.  git wrapper and a handful others
such as receive-pack and upload-pack that need to be directly
invoked via ssh will remain in /usr/bin and the users do not
need to worry about where the rest went.  The recommended way
would be to use non-dash form.  If you care about the extra
indirection done by "git" in your script, run "git --exec-path"
once to get the git binary directory and prepend the result to
PATH.  You _could_ do the latter for your interactive shell
session as well, but it is not actively recommended.

I am not sure what you mean by "second" here.  Did you mean to
say something like this?

    After you did "git-reset --soft somewhereyoudidnotmeantogo"
    by mistake, you can recover with "git-reset --soft ORIG_HEAD".

And probably you meant to say ORIG_HEAD (the latter part of the
documentation you do say ORIG_HEAD).

Now I finally had a chance to finish the command list part.

... and by (obviously) git-repack.

Actually it can take "patch -p1" format patch, and the input
does not have to be git-extended patch.  Two extra things you
can do when the input is git-extended patch is to apply
rename/copy and filemode changes.

I do not think there is any remaining issues with the current
algorithm, so you can mark it final now.

Is there a particular reason to encourage cheating?  IOW, is
mktag cumbersome to use, and if so how?

Not by git barebone Porcelain, but other Porcelains can use it
if they want.  Same thing for git-ssh-fetch.

git-ssh-pull and git-ssh-fetch are the same program, and the
former is only for backward compatibility.  Earlier, only
git-ssh-pull/git-ssh-push pair existed and they continue to
invoke the other on the other end.  Terminology standardized to
call downloading phase "-fetch", and its counterpart "-upload";
so git-ssh-fetch invokes git-ssh-upload on the other end (so
ssh-pull/ssh-push can be viewed obsolete if you want).
