[PATCH] Documentation/git-filter-branch.txt: Fix description of --commit-filter

[Kevin Ballard <kevin@sb.org>]

The old description was misleading and logically impossible. It claimed that
the ancestors of the original commit would be re-written to have the multiple
emitted ids as parents. Not only would this modify existing objects, but it
would create a cycle. What this actually does is pass the multiple emitted ids
to the newly-created children to use as parents.

 As a special extension, the commit filter may emit multiple

 You can use the 'map' convenience function in this filter, and other
 convenience functions, too.  For example, calling 'skip_commit "$@"'
