[PATCH v4 11/22] send-pack: refactor inspecting and resetting status and sending commands

From: Junio C Hamano <gitster@pobox.com>
Date: Sep 5, 2014, 20:54 UTC
Message-ID: <1409950510-10209-12-git-send-email-gitster@pobox.com>
In-Reply-To: <1409950510-10209-1-git-send-email-gitster@pobox.com>

The main loop over remote_refs list inspects the ref status to see if we need to generate pack data (i.e. a delete-only push does not need to send any additional data), resets it to "expecting the status report" state, and formats the actual update commands to be sent.

Split the former two out of the main loop, as it will become conditional in later steps.

Besides, we should have code that does real thing here, before the "Finally, tell the other end!" part ;-)
