>Description:
Shell functions which wrap builtins work at most once.
Once the wrapped builtin is invoked, the shell function is disabled.

It appears that the restructured find_command() code clobbers the
cmdtype member of the hash entry in an inappropriate case. I think
this may have crept in with the changes of Jan 22, 2003.
>How-To-Repeat:
#!/bin/sh

cd() {
	command cd $*
	echo "wrapped cd [new working directory=$(pwd)]"
}

type -V cd
cd .		# shell function executes
type -V cd
cd .		# builtin executes now that wrapping function is lost
type -V cd
