From: Derrick Stolee <derrickstolee@xxxxxxxxxx>
Since 'git bundle' uses setup_revisions() to specify the object walk,
some options do not make sense to include during the pack-objects child
process. Further, these options are used for a call to
traverse_commit_list() which would then require a callback which is
currently NULL.
By populating the callback we prevent a segfault in the case of adding
the --objects flag. This is really a redundant statement because the
bundles are constructing a pack-file containing all objects in the
discovered commit range.
Adding --objects to a 'git bundle' command might cause a slower command,
but at least it will not have a hard failure when the user supplies this
option. We can also disable walking trees and blobs in advance of this
walk.
