  Huh?  #!/bin/sh, #!/bin/csh aren't shell builtins either.  In fact,
  all these scripts are acceptable to execve(2), and the shell won't
  even notice the difference to a binary executable.

I know that, that's not what I said.  Let me repeat myself:

	"By the way, which is inherantly broken when executed as _any_ sort of
	 a script.  It needs to be a shell builtin or it needs to die."

which(1) needs to be a shell builtin, not a sh script, not a csh script, not
a perl script, (and not a binary) to work properly.
