I find that unlikely, because if some system header #defines strchr to
index, they would also have defined strrchr to rindex.  We've been
poisoning rindex for years, so someone would have hollered by now.

(If you're really worried, I can wrap it in ENABLE_CHECKING so that
for a release no one would be affected.  It would only stop developers
from adding index back on mainline.)

But... since Mark is against it, we can wait until 4.1.
