Now that you ask, I don't know. I guess I'm just used to it.

I don't know if commands executed in a chpwd hook function are added to
the history (they shouldn't in my oppinion), but I'm not explicitly
changing it in there. This is a sample .env.rc I'm using in a project:

	# vim:filetype=zsh

	export BASE=$PWD
	export PERL5LIB="$PWD/code/"

	/usr/bin/ctags --languages="Perl" -R "$PWD"

Jonas
