And what does this scheme do when someone makes a hard link to your 
program and invokes it via that hard link?  {In particular, if you are a
nice person and make lots of utilities available, someone might want
access to only one of them, and might prefer to stick with System V/
Bourne shell methods, ruling out symbolic links and aliases.}
