描述

I'd like to be able to specify a few prefixes to exclude from my working copy.

Currently jj sparse set only allows positive patterns. To get what I want, I have to

  • jj sparse set --clear
  • jj sparse set --add everything except the patterns I want to exclude
  • continually repeat that previous step as new paths are introduced

It would be a lot more convenient to just be able to do something like jj sparse set --remove someprefix, or add some negated prefixes via jj sparse set --edit and have it work.

研究方向
The issue requests adding exclusion support to `jj sparse set`. Investigate the sparse checkout implementation in the jj codebase, likely in a file like `lib/src/sparse.rs` or similar. Look for how patterns are currently handled and consider adding a negation syntax (e.g., prefix with `!` or a separate ` remove` flag). Review any existing tests for sparse set to ensure new functionality is properly tested.
