Git bug report git remote get-url

[Nanekrangsan, Sucheela (NYC-GIS)]

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
1. I put [remote] entries in /etc/gitconfig
2. `git config --get remote.xxx.url` returns the correct URL. I can `git pull` from this remote.
3. `git remote get-url xxx` returns "error: No such remote 'xxx'"
4. After `git remote add xxx`, I can get the URL from `git remote get-url`.
What did you expect to happen? (Expected behavior)
I expected `git-remote get-url` to give me the URL I added in /etc/gitconfig. 

What happened instead? (Actual behavior)
`git remote get-url` did not recognize the report I added in /etc/gitconfig.

What's different between what you expected and what actually happened?
I expected the URL from /etc/gitconfig from `git remote get-url` but got error.

Anything else you want to add:
These give me the correct results
`git config --get remote.xxx.url`
`git ls-remote --get-url xxx`

Please review the rest of the bug report below.

This is almost certainly the culprit.

`git remote get-url` doesn't output anything (except the error message
included in your report) when `remote->configured_in_repo` is zero.
Indeed, looking at remote.c:handle_config() where we actually add a new
remote:

    remote = make_remote(remote_state, name, namelen);
    remote->origin = REMOTE_CONFIG;
    if (current_config_scope() == CONFIG_SCOPE_LOCAL ||
        current_config_scope() == CONFIG_SCOPE_WORKTREE)
            remote->configured_in_repo = 1;

we only set configured_in_repo when we're looking at local or
worktree configuration. Since $(prefix)/etc/gitconfig isn't either of
those, we'll avoid setting configured_in_repo, hence we'll end up inside
of this if-statement in builtin/remote.c:get_url():

    remote = remote_get(remotename);
    if (!remote_is_configured(remote, 1)) {
            error(_("No such remote '%s'"), remotename);
            exit(2);
    }

...producing the error message in your report.

This makes sense, since `git remote add` will configure the remote `xxx`
in your repository-local configuration, not the system-wide one.
