Subject: Completing multiple states with _arguments

Hi!

How do I deal with multiple states when completing with _arguments?

local context state line
typeset -A opt_args

_arguments \
  ':: :->something-optional-before-files' \
  '*:: :->file' && ret=3D0

# Now what?

The documentation doesn=E2=80=99t give an example, neither does the book, a=
nd
I was unable to find an example under Completion in the source tree.

I=E2=80=99m updating the git-diff completion (along with all the other git-=
*
completions), if you want a more specific example.  Git diff can take
two arguments that may be commits, trees, or blobs before it takes any
file arguments.

Thanks!
