Add -- before %f in the smudge/clean filter configuration

Browse source 
To support filenames starting with dashes.

To update the config of existing repositories, you can re-run git-annex init.

Perhaps it should check every time for the old config and update it, but
that has several problems:

	- read-only repos
	- unexpected commands like `git annex find` changing git configs
	  might be surprising behavior

Since filenames starting with dashes are not super common and the user can
re-init easily enough if their repo needs fixed, I went for the simplest
fix.

No need to complicate this with Android, this is sufficient to reproduce
the problem:
joey@darkstar:/tmp/a>touch ./-foo
joey@darkstar:/tmp/a>git add ./-foo
Invalid option `-foo'
Usage: git-annex smudge (FILE [--clean] | --update)
error: external filter 'git-annex smudge --clean %f' failed 1
The fix is to edit .git/config to contain:
[filter "annex"]
smudge = git-annex smudge -- %f
clean = git-annex smudge --clean -- %f
The added -- before the filename prevents confusing it with an option.
I've done this for new git-annex repositories, and `git annex init` will
also update existing repos.
