[PATCH v2] log --children
Teach git-log to support --children, which was added by f35f5603f4 to the revision machinery, and by 72276a3ecb to rev-list, but was never added to git-log.
Also add tests for 'log --children' and 'log --parents'.

They are mutually exclusive:
$ git log --parents --children fatal: cannot combine --parents and --children

Good idea. :-)
