ls -l obscures important information

[haynes at ucbarpa.Berkeley.EDU.UUCP]

I had a maddening problem in which a member of a group could not
execute a program that was setgid to that group.  After some fuddling
around I chmoded the program again and suddenly it worked.  Turned
out that a mistake in a makefile had caused the program to be
installed originally with mode 2701 - not executable by the group -
but of course ls -l shows  rwx--s--x   as if all were well.
