diff: fix 2 whitespace issues

When whitespace or whitespace change was ignored, the function
xdl_recmatch() returned memcmp() style differences, which is wrong,
since it should return 0 on non-match.

Also, there were three horrible off-by-one bugs, even leading to wrong
hashes in the whitespace special handling.

The issue was noticed by Ray Lehtiniemi.

For good measure, this commit adds a test.
