[PATCH 3/3] log: add tests for messages containing CRLF to t4202

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

A previous commit fixed a bug in the ref-filter API causing messages
containing CRLF to be incorrectly parsed and displayed.

Add a test to also check that `git log` correctly handles such messages,
to prevent futur regressions.
