feature request: set option -t if argv[0] == 'pxz'

[jowagner]

As indicative from issue #65 people may be surprised that pixz can modify the payload. I understand your reasons for not wanting to make '-t' the default.

A simple solution is to have the installer to create a symlink pxz --> pixz, to check argv[0] in the code, set '-t' if the name is 'pxz' and to add a synopsis and description line in the man page.

I believe there's another program out there called pxz, we probably don't want to steal their name. Could you just set an alias if this is the behaviour you want?

How then about parallelxz? The point is that having two names documented in the man page much stronger draws attention to the tar-specific behaviour of pixz (reflected in the i in the name) than the current documentation.
