Git and VCS

Part of src/cmds/ — see also docs/contributing/TECHNICAL.md

Specifics

• git.rs uses trailing_var_arg = true + allow_hyphen_values = true so native git flags (--oneline, --cached, etc.) pass through correctly
• Auto-detects --merges flag to avoid conflicting with --no-merges injection
• Global git options (-C, --git-dir, --work-tree, --no-pager) are prepended before the subcommand
• Exit code propagation is critical for CI/CD pipelines
• glab_cmd.rs declares -R/--repo and -g/--group at the clap level; they are appended to the glab args (not prepended) so subcommand dispatch stays intact
• has_output_flag() short-circuits to passthrough when the user explicitly requests -F / --output / --json (avoids double JSON injection)
• should_passthrough_view() redirects mr/issue view to passthrough when --web or --comments is set
• JSON handlers use the local run_glab_json<F>() helper wrapping runner::run_filtered + RunOptions::stdout_only().early_exit_on_failure().no_trailing_newline(); on JSON parse error, falls back to the raw stdout (glab sometimes emits plain text for empty results)
• ci status uses text-keyword parsing (glab doesn't support -F json for this subcommand); when no English status keyword is recognized (non-English locale), returns raw verbatim
• ci trace uses ANSI-stripping + GitLab section-marker filtering + runner/git/artifact boilerplate removal; kept as text-only filter, not JSON
• release list falls back to raw output when the glab 1.82+ format doesn't match the legacy tab-delimited parser
• Pipeline / merge-status indicators use text tags ([ok], [fail], [cancel], [run], [pend], [skip], [conflict]) to match gh_cmd.rs and avoid multi-byte rendering quirks

Cross-command

• gh_cmd.rs imports compact_diff() from git.rs for diff formatting; markdown helpers (filter_markdown_body, filter_markdown_segment) are defined in gh_cmd.rs itself
• glab_cmd.rs also uses compact_diff() from git.rs for mr diff; its filter_markdown_body is currently duplicated from gh_cmd.rs (shared-module refactor deferred)
• diff_cmd.rs is a standalone ultra-condensed diff (separate from git diff)
