vim-patch:77cfc49: runtime(python): highlight ellipsis literals
The ellipsis literal (`...`) can be used in multiple contexts:
- Placeholders: `class Foo: ...`
- Containers: `Tuple[int, ...]`
- Assignments: `x = ...`
This is a trickier pattern to match because we can't rely on keyword
boundaries, so we instead look for exactly three dots (`...`).
This does mean that we will match the `...` portion of `x...x`, which
isn't valid Python syntax, but I think that's an acceptable trade-off
that avoids making this pattern much more complex.
