Patch for the resticted behaviour

X-seq: zsh-workers 5754
From: Lehti Rami <rammer@xxxxxxxxx>

Subject: Patch for the resticted behaviour
Date: Thu, 11 Mar 1999 11:33:53 +0200
Mailing-list: contact zsh-workers-help@xxxxxxxxxxxxxx; run by ezmlm
Reply-to: rammer@xxxxxxxxx

Hi!

The attached patch adds a new compiletime configuration option.
If configure is given the new --disable-resticted-r option 
the resulting zsh does not make the shell restricted when 
the basename of the invoked command starts with r.

This does patch does NOT change the default behaviour of zsh.

Please include this in the next release of zsh.
If you want to reply to me please use my direct e-mail address because 
I'm not on the zsh-workers list.

Rami Lehti
