Perhaps we should die at this point so that...

the user does not have to see this.

In other words, instead of this:

>  http_fetch () {
>  	# $1 = Remote, $2 = Local
> +	type curl >/dev/null 2>&1 ||
> +	    die "The curl program is not available"
>  	curl -nsfL $curl_extra_args "$1" >"$2"
>  }

something like this, perhaps:

	http_fetch () {
        	# $1 = remote, $2 = local
               	curl -nsfL $curl_extra_args "$1" >"$2" || exit
	}

Then the shell would say "curl: command not found" and we would
stop.

I am just hestating to use "type" there (yeah, I know mergetool
has one but that one is not as close to the core of the workflow
as git-fetch is).

BTW, isn't it a packaging bug not to depend git-fetch on curl?
