Sounds sensible.

Yup, that is exactly my thought when I responded to your v1.

It is somewhat unfortunate that we do not say what the name of the
"origin" is anywhere in the resulting configuration file. The only
way to tell that "--origin somewhere" was used is to notice that
there is only one remote and its name is "somewhere". Instead of
"usually the thing is called 'origin', so let's make sure it does
not exist", we may want to say "there is only one remote and it is
called somewhere because that is how we named it", i.e.
git -C clone-bare config --name-only \
--get-regexp "remote\..*\.url" >actual &&
echo remote.somewhere.url >expect &&
test_cmp actual expect
But stepping back a bit, I think this shows another reason why use
of '--origin' with '--bare' as-is may not be so pleasant to use.
In a repository _with_ working tree, this lack of "what is 'origin'
called in this repository?" is not a problem because you'd get these
after cloning:
[remote "somewhere"]
url = ...
fetch = ...
[branch "master"]
remote = "somewhere"
merge = refs/heads/master
You can say "git fetch" or "git pull" without the remote name and we
will know which remote to interact with, because our branch knows
which remote to fetch from.
In a bare repository, however, you only get this:
[remote "somewhere"]
url = ...
I do not think "git fetch" in such a repository knows that it needs
to fetch from 'somewhere', even whe it is the only remote repository
available to us.
We may need a bit _more_ work (e.g. leave an optional configuration
remote.originName = "somewhere" when "--bare --origin somewhere" is
used, and teach "git fetch" to pay attention to it, instead of
assuming 'origin') before "--bare --origin somewhere" becomes truly
usable. And I suspect that "git fetch" is not the only one that
needs such "fix".
