I think this looks mostly good (a few comments below), one thing is taht
the test-miscprint test isn't run by the 'make libflash-check' target,
so it'll have to be added to libflash/test/Makefile.check so that we can run it
automatically.

Although... there's libflash versus pflash tests too... I know Cyril has
been working on some pflash tests, but the libflash ones just need to
call the API to do the tests.

Your indenting here is off.
