log, show: add tests for messages containing CRLF

A previous commit adjusted the code in ref-filter.c so that messages
containing CRLF are now correctly parsed and displayed.

Add tests to also check that `git log` and `git show` correctly handle
such messages, to prevent futur regressions if these commands are
refactored to use the ref-filter API.
