[Rpm-maint] [rpm-software-management/rpm] rpm2cpio and rpm2archive: don't write archive data to a terminal. (#116)

[Peter Jones]

rpm2cpio and rpm2archive happily write binary data to the output
terminal.  This happens, for example, when I'm typing a command such as
"rpm2cpio foo.rpm | less" and I make a typo, hitting <Return> instead of
the pipe key.  This often results in hilarious (if bewildering) font and
character encoding changes.  On some systems, this can even result in
installation of relatively arbitrary rpms!

Nobody has ever meant to do this, and it's easy to prevent, so that's
what this patch does.
