Summary: Be careful with the clash of aliases, functions, and builtins.

Actually, you have to quote the cd within chdir to retain it's orginal meaning.
Otherwise you've set up a recursive call to the alias cd:

	alias cd=chdir
	function chdir
	{
		'cd' $1
		PS1="$PWD >"
	}

I discover this while trying to modify cd to fit in with my pushd and popd
functions.
