Spotted by Coverity: if you _just_ gave a filename to bidi_test, without any previous argument that set testfn to something other than NULL, the program would crash rather than giving an error message. (It's only a test program, but test programs you only run once in a blue moon are the ones that _most_ need to explain their command-line syntax to you carefully, because you've forgotten it since last time you used them!) Also, conditionalised a memcpy on the size not being 0, because it's illegal to pass a null pointer to memcpy _even_ if size==0. (That would only happen with a test case containing a zero-length string, but whatever.)
