From 30415d50cccef0ec22bb4a6d58138760b142758d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 10 Sep 2007 23:03:15 -0400 Subject: [PATCH] Move bundle specific stuff into bundle.[ch] The transport specific stuff was moved into libgit.a, and the bundle specific stuff will not be left behind. This is a big code move, with one exception: the function unbundle() no longer outputs the list of refs. You have to call list_bundle_refs() yourself for that.
