[REBOL] Re: clean-path

The main reason that URLs are not translated by clean-path is
basically that you do not really know what directory transaltion is in
effect on the contacted site. Take FTP as an example:
read ftp://user1:[pass--example--com]/readme.txt
This file will most likely reside in /home/user1/readme.txt.
Now lets say that user1 has shared their directory and this file for
others to read. So user2 wants to get it:
read ftp://user2:[pass2--example--com]/../user1/readme.txt
This will work because the "root" directory that is specified by
ftp://user2:[pass2--example--com]/ is actually in /home/user2/. The
problem with cleaning the URL is this:
clean-path ftp://user2:[pass2--example--com]/../user1/readme.txt would
come out as:
ftp://user2:[pass2--example--com]/user1/readme.txt
which is clearly not right.
Some FTP servers will not allow you to back out of your home directory
but some do. The point is that we don't know so we leave it open and
do no translation.
