By the way, my suggestion of `{{[^W]}}` was to match any character except `W`.
`{{^\W}}` looks for `W` at the beginning of the line: `^` outside of character
set matches the beginning of the line, `\W` is just going to match `W`, I
think. It doesn't suppose character classes starting with `\` such as `\W`.
Instead, you have to use the ones like in my last comment.
Here's a source that I think matches what FileCheck supports pretty well:
