[PATCH] fetch-pack: avoid packing reachable objects.

[Jan Harkes <jaharkes@cs.cmu.edu>]

Mark remote commits that were found in the alternate repository as
COMPLETE and avoid unnecessary packing of already available objects.

When we pull updates from a shared repository into a clone that was
created with 'git clone -l -s', we pack objects that are already
reachable. This was because we only marked local refs as COMPLETE.
