-# Drupal git normalization
-# @see https://www.kernel.org/pub/software/scm/git/docs/gitattributes.html
-# @see https://www.drupal.org/node/1542048
-# Normally these settings would be done with macro attributes for improved
-# readability and easier maintenance. However macros can only be defined at the
-# repository root directory. Drupal avoids making any assumptions about where it
-# is installed.
-# Define text file attributes.
-# - Treat them as text.
-# - Ensure no CRLF line-endings, neither on checkout nor on checkin.
-# - Detect whitespace errors.
-#   - Exposed by default in `git diff --color` on the CLI.
-#   - Validate with `git diff --check`.
-#   - Deny applying with `git apply --whitespace=error-all`.
-#   - Fix automatically with `git apply --whitespace=fix`.
