- A top-level .gitattributes sets the attribute 'text=auto' for all
files in the repo, enabling line-ending normalization
- A `git add --renormalize` run converted any existing CRLF files
to the canonical LF format.
- 'text=auto' permits Git on Windows to convert files to CRLF
automatically on checkout, for convenience. Any commits
added will be converted back to the repo format for checkin.
