[cgiwrap-users] cleaner SCRIPT_NAME from REDIRECT_URL

[san <san...@co...>]

For redirect-based setups I made a patch to ciwrap-3.7
so to have a cleaner SCRIPT_NAME. 

Right now it is always constructed using apache setted SCRIPT_NAME
(tipically /cgi-bin/cgiwrap) and appending to it the username and
the script relative path. This brings to a working but unclean url
because in cases in which redirection takes place it would be
better to have a yet-to-redirect SCRIPT_NAME.

	OLD WAY: /~user/script.cgi -> /cgi-bin/cgiwrap/user/script.cgi
	PATCHED: /~user/script.cgi -> /~user/script.cgi

This is accomplished by the use of the (NON-STANDARD) REDIRECT_URL
variable when set.
