example startup file

[Oliver Kiddle <opk@xxxxxxxxxxxxx>]

This is a suggestion for the example zshrc in StartupFiles. I think we
should be encouraging the use of new style completion so the main
change here is to enable it. All deleted compctls have equivalent or
similiar examples in compctl-examples.

I think I've managed to put together a reasonably varied selection of
mostly simple zstyles including one zstyle -e example.

I've not commited this yet to allow for any objections.

Also, I'm not too happy with the autoload for loop: if it finds no
executable files in a directory it emits an error and returns. Does
anyone have any better suggestions which keep things simple. As I see
it, you either also loop for files or use the N nullglob flag and
redirect outout because autoload with no arguments outputs all
functions.

I get directories in fpath duplicated with this .zshrc after compinit
which isn't too good. Maybe typeset -U fpath should be the default?

Etc/FEATURES could also do with an update before 4.0.1. At the very
least to update the count of options, builtins etc. I'm a bit concerned
about the line which says:
	directory stack access with =num
Either this is wrong, has been broken or I'm misunderstanding it.
