o (#63751)
# Objective In Vim mode, pressing `o` to open a line inside a documentation-style block comment preserves indentation but drops the `* ` prefix. The behavior for pressing Return is already correct as it continues this prefix in the next line. This change makes both actions behave consistently. Fixes #55049 ## Solution Make Vim’s `o` and `O` commands copy documentation-comment prefixes such as `* ` onto the new line. This happens only when the current line is parsed as a comment. Also added regression coverage for this and folded it into the existing `test_o_comment` test. ## Testing - `CC=clang CXX=clang++ cargo test -p vim test_o_comment -- --nocapture` - `CC=clang CXX=clang++ cargo test -p vim` - `CC=clang CXX=clang++ cargo test -p multi_buffer` - `cargo fmt --all -- --check` - `CC=clang CXX=clang++ ./script/clippy -p vim -p multi_buffer` - Tested on Linux aarch64. ## Self-Review Checklist: - [x] I reviewed the diff for quality, security, and reliability - [x] Unsafe blocks, if any, have justifying comments - [x] The content adheres to the Zed UI standards - [x] Tests cover the changed behavior - [x] Performance impact is acceptable --- Release Notes: - Fixed Vim `o` comment continuation in C-style multiline comments.
