diff: add tests for --relative without optional prefix value

Browse Source 
We already have tests for --relative, but they currently only test when
a prefix has been provided. This fails to test the case where --relative
by itself should use the current directory as the prefix.

Teach the check_$type functions to take a directory argument to indicate
which subdirectory to run the git commands in. Add a new test which uses
this to test --relative without a prefix value.
