From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx>
Teach rev-list to use the filtering provided by the
traverse_commit_list_filtered() interface to omit
unwanted objects from the result.
This feature is only enabled when one of the "--objects*"
options are used.
When the "--filter-print-manifest" option is used, the
omitted objects and their sizes are printed at the end.
These are marked with a "~". This can be combined with
"--quiet" to get a list of just the omitted objects.
