I don't know what these checks are doing but maybe this makes sense or
not - I don't know.

Ah, thanks for the information.

Title:
  Ability to write compressed data to stdout

Status in “xz-utils” package in Ubuntu:
  Invalid

Bug description:
  I'm using Ubuntu 14.04 dev with xz-utils 5.1.1alpha+20120614-2ubuntu2
  and xz-utils provides the option -c to write to stdout but
  interestingly this doesn't work with compressed data:

  sworddragon at ubuntu:~/tmp$ xz -c 1
  xz: Compressed data cannot be written to a terminal
  xz: Try `xz --help' for more information.

  
  As compressed data is not uncommon for a compressing application maybe writing compressed data to stdout can be supported too.
