>Description:
uudecode -o doesn't work if the output is piped to other programs.
	
>How-To-Repeat:
 $ uudecode -o /tmp/a.tgz </tmp/a.uue
 $ tar tvzf /tmp/a.tgz
 drwxr-xr-x user/user         0 Nov 13 13:10 2001 dir/
 -rw-r--r-- user/user         3 Nov 13 13:10 2001 dir/file
 drwxr-xr-x user/user         0 Nov 13 13:10 2001 dir/RCS/
 -r--r--r-- user/user       307 Nov 13 13:10 2001 dir/RCS/file,v
 $ uudecode -o /dev/stdout </tmp/a.uue | tar xvzf -
 uudecode: /dev/stdout: stdin: Invalid argument
 
 gzip: stdin: unexpected end of file
 tar: child returned status 1
	
>Fix:
This patch could be a solution, but doesn't solve the below though I
don't think it's useful.

$ uudecode -o /tmp/a.tgz </tmp/*.uue | tar xvzf -

By the way, I don't understand the mean of the following lines. Are they
necessary? If they can be zapped, it could be a better solution.
