'exit(1);' considered useless (slight flame)

I'd rather that the shell went through the trouble of checking for the
exact cause of an error, instead of forcing me to do it.  The code to do
this checking need not even be in the shell -- when an error occurs, the
shell can call some other code to track down the error to something more
specific than "Permission denied".  If you're really clever, you might
make the further search and elaboration a user-settable option...
