bzip2 does not exit after showing license as requested with --version
or --license as most apps would do, instead it waits for data to
compress on stdin. Because of that, if `bzip2 --version' is called,
bogus `bzip2: I won't write compressed data to a terminal' error
message will be displayed, and checking for bzip2 version in scripts
as in
bzip2 --version 2>&1 | grep -o "Version [^,]*"

this by exiting right after showing version/license text.
