How do I exclude files from jj fix

[anka-213]

I wasn't able to figure out the syntax to exclude files, only how to make an explicit whitelist. The examples in the documentation only mention includes, not excludes: https://jj-vcs.github.io/jj/latest/cli-reference/#jj-fix and https://jj-vcs.github.io/jj/latest/config/#enforce-coding-style-rules only mention things like:

[fix.tools.clang-format]
command = ["/usr/bin/clang-format", "--assume-filename=$path"]
patterns = ["glob:'**/*.cc'",
            "glob:'**/*.h'"]

I tried using ! as mentioned by https://docs.rs/glob/latest/glob/struct.Pattern.html linked from https://jj-vcs.github.io/jj/latest/revsets/#string-patterns, but that gave syntax error.

These are filesets.

For example, all Python files except those in a particular directory might be:

root-glob:”**/*.py” ~ root:”vendor”
