Well, the disappearance isn't mysterous.  I removed it when I changed
execcmd() to use the CFLAG_FAKE_EXEC flag.  That's why I was making
test releases so we could catch these types of bugs before the release.
But it appears no one tried it out.

Anyway, I'll probably make a beta11a in the next couple of days to
correct some of these problems.
