Re: [PATCH 3/4] remote: actually check if remote exits

> When converting the git remote command to a builtin in 211c89 ("Make
> git-remote a builtin"), a few calls to check if a remote exists were
> converted from:
>        if (!exists $remote->{$name}) {
>        	  [...]
> to:
>        remote = remote_get(argv[1]);
>        if (!remote)
>           [...]
