Summary: 'unbuffer' eats exit codes of the programs

Initial Comment:
Try:

$ unbuffer cat /sdlfjsdlfjsld
   cat: /sdlfjsdlfjsld: No such file or directory
$ echo $?
   0

I don't know if this is intentional, but I believe (and seems to be more logical for me), that the result should be 1. What do you think?

Proposed patch fixes the script when called without '-p' arg. There will be probably also necessary fix behaviour when unbuffer is called with '-p' arg, but I didn't explore that.
