Remove zsh, which is older than the version in pkgsrc/zsh-current.
Sorry Blair :)

Log message:
Import zsh-4.3.6 as wip/zsh.

This is the start of a reworking of zsh-current to be more pkgsrc-
and user- friendly.

goals:	- provide coherent terminal type selection facility
	- provide facility (using PRINT_PLIST_AWK, etc) to ease installation
	  of completion scripts.
	- Set site function-dir and others in accordance with pkgsrc
	  policy (?).
	- Support as many platforms as possible, consdering the recommended
	  options, e.g. using zsh's own memory allocator, etc.
	- test

	I don't have much time to work on this, so others are most welcome!
