In anticipation of modifying this behaviour, add a test verifying the handling of exclamation marks when looking up a commit "by name".

Specifically, as documented: '^{/!Message}' should fail, as this syntax is currently reserved; while '^{!!Message}' should search for a commit whose message contains the string "!Message".
