--unpacked::
Only useful with `--objects`; print the object IDs that are not
in packs.
+
+--filter=<filter-spec>::
+ Only useful with one of the `--objects*`; omits objects (usually
+ blobs) from the list of printed objects. The '<filter-spec>'
+ may be one of the following:
++
+The form '--filter=blob:none' omits all blobs.
++
+The form '--filter=blob:limit=<n>[kmg]' omits blobs larger than n bytes
+or units. The value may be zero.
++
+The form '--filter=sparse:oid=<oid-ish>' uses a sparse-checkout
+specification contained in the object (or the object that the expression
+evaluates to) to omit blobs that would not be not required for a
+sparse checkout on the requested refs.
++
+The form '--filter=sparse:path=<path>' similarly uses a sparse-checkout
+specification contained in <path>.
+
+--filter-print-omitted::
+ Only useful with `--filter=`; prints a list of the objects omitted
+ by the filter. Object IDs are prefixed with a ``~'' character.
+
+--missing=<missing-action>::
+ A debug option to help with future "partial clone" development.
+ This option specifies how missing objects are handled.
++
+The form '--missing=error' requests that rev-list stop with an error if
+a missing object is encountered. This is the default action.
++
+The form '--missing=allow-any' will allow object traversal to continue
+if a missing object is encountered. Missing objects will silently be
+omitted from the results.
++
+The form '--missing=print' is like 'allow-any', but will also print a
+list of the missing objects. Object IDs are prefixed with a ``?'' character.
