I just discovered that "who am i" prints nothing if stdin is a ptty.
It gets the name from ttyname, then searches /etc/utmp for a line
matching the ptty.  Since no one is logged in on a ptty it fails.

This was observed under Pyramid OS-X which pretends to be both BSD and
SysV.

This is a problem with OSx 2.3.... Pyramid maintained such a separation
between 4.2 and SysV that the SysV end knows nothing about people logged in
under Ethernet, a problem since corrected under OSx 2.5.
