A git commit message highlighter being nicer than the built-in one.

Highlighting inspiration from https://cbea.ms/git-commit.

• Inform about git commit -v if it isn't being used
• Proper git commit -v diff highlighting even when running git in not-English.
• Highlight file names and what's happening to them
• Report > 72 characters subject lines as errors
• Report > 50 characters subject lines as warnings
• Report not-capitalized subject lines as errors (with Quick Fix)
• Report errors for trailing punctuation
• Report errors for non-blank second lines

• Comes with tests using https://github.com/PanAeon/vscode-tmgrammar-test
• Comes with unit tests for the diagnostics

• Add Quick Fixes for some of our diagnostics
• Update the screenshot
• Make an icon
• Highlight current branch name in the Git metadata
• Mark commit message subject line with:
  • DONE: meta.scope.subject.git-commit
  • meta.scope.subject-after-50.git-commit from character 51 and onwards
  • meta.scope.subject-after-72.git-commit from character 73 and onwards
• Make sure diagnostics are applied to newly opened files, not just on file edits
• Have unit tests that don't launch VSCode
• Move all tests under the same top subdirectory
• npm test in CI
• Validate code formatting in CI

To run the unit tests:

npm install && npm test

To install into VSCode:

1. npm run package
2. In VSCode:
   • Click Extensions
   • Click the ... menu in the top right corner
   • Click Install from VSIX...

To check highlighting in VSCode: "Developer: Inspect Editor Tokens and Scopes"

To publish a new version:
