Oops.  Fixed:

This patch adds some memrchr tests for len == 0 and for positions close
to the beginning, which are equivalent to positions close to the end for
memchr.

* string/test-memrchr.c (test_main): Add tests for len == 0 and
for positions close to the beginning, which are equivalent to
positions close to the end for memchr.
