Tommy,
your haystack[] variable is long and complex.  Can you get
the same testing out of a shorter sample string?

Can you add a comment for each little check, translating it into english?

All your tests seem to use the FR_MATCHCASE and FR_DOWN flags,
could you also test without those flags a bit more?

How sure are you about the bugfix?  Are there other places in the
source where a similar off-by-one error is made?

Otherwise this looks great.
