Subject: [PATCH] git-fetch: Fix Argument list too long
Message-ID: <87wt02nb8d.fsf@duaron.myhome.or.jp>
URL: https://gitlist.dev/e/87wt02nb8d.fsf%40duaron.myhome.or.jp

```
If $ls_remote_result was too long,

    git-fetch--tool -s pick-rref "$rref" "$ls_remote_result"

in git-fetch will fail by "Argument list too long".

This patch fixes git-fetch--tool and git-fetch by reading
$ls_remote_result from stdin.
