>Release:        FreeBSD 2.2.6-RELEASE i386
>Environment:

Observed on 2.2.6-RELEASE, but it appears that all versions of fetch(1)
in the CVS tree have this problem.

>Description:

"fetch -o - url://file/name" generally retrieves the URL to stdout.  
However, in the case of "file:/" URLs, fetch(1) creates a file called 
"-" in the current directory, containing the file contents.

>How-To-Repeat:

fetch -o - /etc/hosts
cat ./-

>Fix:
