From b7a025d921e416a708eb2d664d9ff51b303edd97 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Fri, 6 Jan 2012 15:12:31 +0100 Subject: receive-pack: move more work into write_head_info() Move some more code from the calling site into write_head_info(), and inline add_alternate_refs() there. (Some more simplification is coming, and it is easier if all this code is in the same place.) Move some helper functions to avoid the need for forward declarations.
