This helps "git fetch --quiet" stay quiet. Thanks for the resend; I think this got lost in the shuffle between releases. This version addresses my complaints about the original; I don't see any reason it shouldn't be applied. -Peff ``` ## Junio C Hamano, 2011-07-12 16:09 Subject: Re: Resend: [PATCH] Do not log unless all connect() attempts fail Message-ID: <7v39iba3b2.fsf@alter.siamese.dyndns.org> URL: https://gitlist.dev/e/7v39iba3b2.fsf%40alter.siamese.dyndns.org In-Reply-To: ``` This looks Looks good to me; could you sign-off the patch, please?
