Documentation: filter-branch: document how to filter all refs

Browse source 
Document the '--' option that can be used to pass rev-list options
(not just arguments), and give an example usage of '-- --all'.  Remove
reference to "the new branch name"; filter-branch takes arbitrary
arguments to rev-list since dfd05e3.

<rev-list options>...::
When options are given after the new branch name, they will
be passed to 'git-rev-list'. Only commits in the resulting
output will be filtered, although the filtered commits can still
reference parents which are outside of that set.
Arguments for 'git-rev-list'. All positive refs included by
these options are rewritten. You may also specify options
such as '--all', but you must use '--' to separate them from
the 'git-filter-branch' options.

Now, you will get the rewritten history saved in HEAD.
To rewrite the repository to look as if `foodir/` had been its project
root, and discard all other history:
-------------------------------------------------------
git filter-branch --subdirectory-filter foodir -- --all

Thus you can, e.g., turn a library subdirectory into a repository of
its own. Note the `\--` that separates 'filter-branch' options from
revision options, and the `\--all` to rewrite all branches and tags.
To set a commit (which typically is at the tip of another
history) to be the parent of the current initial commit, in
order to paste the other history behind the current history:
