+--remap-to-ancestor::
+ Rewrite refs to the nearest rewritten ancestor instead of
+ ignoring them.
++
+Normally, positive refs on the command line are only changed if the
+commit they point to was rewritten. However, you can limit the extent
+of this rewriting by using linkgit:rev-list[1] arguments, e.g., path
+limiters. Refs pointing to such excluded commits would then normally
+be ignored. With this option, they are instead rewritten to point at
+the nearest ancestor that was not excluded.
--prune-empty::
Some kind of filters will generate empty commits, that left the tree
point to the top-most revision that a 'git-rev-list' of this range
will print.
+If you need to add 'Acked-by' lines to, say, the last 10 commits (none
+of which is a merge), use this command:
+
+--------------------------------------------------------
+git filter-branch --msg-filter '
+ cat &&
+ echo "Acked-by: Bugs Bunny <bunny@bugzilla.org>"
+' HEAD~10..HEAD
+--------------------------------------------------------
+
*NOTE* the changes introduced by the commits, and which are not reverted
by subsequent commits, will still be in the rewritten branch. If you want
to throw out _changes_ together with the commits, you should use the
