Detailed Description

This testcase builds on check-xor.c to verify that:.

• the dummy-test has a read and write hook,
• the read and write hook actually edit/alter the buffer
• the read hook reverses whatever the read hook did

This testcase can be used to similar test any other plugin during development.

Many of the build-up tests that this testcase does are previously verified by check-xor.c, so they are compressed into one-line maintenance nightmares to reduce the on-screen realestate. I'm not a fan typically of compressed onscreen realestate (which is why I favour my coding style, but that's a holywar): compressed code is more difficult to maintain, newer engineers and gurus alike; this is a testcase.
