if stdin is a real tty, stdout can be a real tty or be redirected, as
before.

Sorry about that, I should have added a explicit command line option,
like with 'perf', where '-' means stdin. As this is a relatively new
feature I guess I'll do just that, i.e. stop unconditionally checking
for isatty(0) and only use the pretty printer when --printer is used.

Well, you'll at least need to update pahole to 1.22, or, in the
meantime, use a patch, I'm working on it now, thanks for the report!
