I am not sure "works as well" is a good enough justification to choose a
Porcelain command over a plumbing command in this particular context.
After all, filter-branch is a scripting enviornment, isn't it?

There also is another subtle difference.  "git rm" takes pathspecs while
"update-index" takes paths.

So after running one of these commands:

	$ git rm --cached 'Makefil?'
	$ git update-index --force-remove 'Makefil?'

output from:

	$ git diff --cached --stat

would be different.
