memset(blah, 0, sizeof(blah)) is the common case, and not having to say
0 is 4 bytes smaller.  Once there are about 3 uses of it, I'd wind up
putting a wrapper in lib/lib.c anyway.  Obsoleting that was silly on the
part of the standards guys.

rindex() is just habit, strrchr() is a gratuitous rename, I don't care
either way and can fix that up if it's throwing warnings for you...
