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

[Dave Decot]

Perror() is not good because it discourages specific messages.  The shells
should say:

    % file
    file: data; not executable
or
    file: program not executable by you

instead of

    % file
    file: permission denied

Also, why do we get:

    % cd /user/bin
    /user/bin: No such file or directory

when the argument to cd is never supposed to be a file?  Somebody used
the convenient perror() instead of writing a specific message.
