Fixes #4843

Black was incorrectly removing comments that precede # fmt: off/# fmt: on blocks, particularly affecting Jupytext's # %% [markdown] comments.

Description

Black 25.11.0 introduced a regression where comments before fmt:off blocks were removed. This broke Jupytext percent format files.

Example:

# Before:
# %% [markdown]
# fmt: off
# fmt: on

# After Black (broken):
# fmt: off  
# fmt: on

Root cause: Recent fmt:off/on changes didn't preserve prefix comments when creating STANDALONE_COMMENT nodes.

Fix: Updated _handle_comment_only_fmt_block and visit_STANDALONE_COMMENT to preserve non-fmt comments while maintaining fmt block formatting.

Checklist

  • Add an entry in CHANGES.md? Yes
  • Add / update tests? Yes - added jupytext_markdown_fmt.py
  • Implement under --preview? N/A - bugfix only
  • Update documentation? N/A - restores existing behavior

Testing: All existing tests pass (197/197). Added comprehensive test coverage.

Fixes psf#4843

Black was incorrectly removing comments that precede fmt:off/on blocks,
particularly affecting Jupytext's markdown comments like # %% [markdown].

The issue occurred in two places:
1. _handle_comment_only_fmt_block wasn't preserving pre-fmt comments
2. visit_STANDALONE_COMMENT bypassed prefix processing for fmt blocks

This fix:
- Improves prefix calculation to preserve all pre-fmt:off content
- Enhances STANDALONE_COMMENT handling to process prefix comments
  while preserving fmt block formatting
- Adds comprehensive test coverage

All existing tests pass and the original issue is resolved.
- Fix line break and indentation issues in comments.py
- Fix line length and formatting issues in linegen.py
- Split long condition for better readability
- Resolve merge conflict markers in linegen.py
- Fix indentation issues in comments.py
- All syntax errors now resolved

pre-commit checks still fail due to mypy CI issue.
i need further assistance.
it can be issue with pytest.

Looks like pytest is now minimum python >=3.10, and since black is still 3.9 that's also what mypy uses, hence the "match statements don't exist" error inside pytest. We'll either need to get #4842 out to also have the 3.10 minimum, or temporarily limit the pytest version.

Merged. Rebase away.

hey @cooperlees i am having conflicts with my rebase. can you help.
i am confused as pre-commint checks are completed succesfully.

Edit : I mistakenly thought there is a need for the rebase of my branch.
I tried my best to not commit unnecessary commits.

The pre-commit does not include the failing check, which makes sure that the repo is always formatted with the changes to main (hence the name "format ourselves"). To fix this, you need to run black on itself, which I usually do with py src/black/__init__.py <path to file>, though there might be other ways. You can see the names of the files that need re-formatted in the failing tests, those being

would reformat /home/runner/work/black/black/src/black/comments.py
would reformat /home/runner/work/black/black/src/black/linegen.py

thank you @MeGaGiGaGon for the solution, there is no conflict this time. :)

##### Integrations

- If using stdin with `--stdin-filename` set to a force excluded path, stdin won't be
