In anticipation of extending this behaviour, add tests verifying the
handling of exclamation marks when looking up a commit "by name".
Specifically, as documented: '<rev>^{/!Message}' should fail, as the '!'
prefix is reserved; while '<rev>^{!!Message}' should search for a commit
whose message contains the string "!Message".
