>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.
} else if (!freopen(buf, "w", stdout) ||
fchmod(fileno(stdout), getmode(mode_handle, 0) & 0666)) {
warn("%s: %s", buf, filename);
