First prize goes to Rich Schultz <rich@ccrwest.org> who says:

This has nothing to do with the automounter. The lstat system call has changed
in 4.1.3. Whether this is a bug or a feature, I still don't know, although I
have told the Sun hotline about it.
In 4.1.2, lstat("foo",...), where "foo" is a symbolic link, returns status
about the link, but lstat("foo/",...) returns status about the directory to
which foo points. The trailing "/" is significant. In 4.1.3, the trailing "/"
is no longer significant, and both lstat calls return status about the link.
You can see the effect in the "ls" command, which uses lstat. If you try
ls -l ~user/.
you'll see your old stuff again.

Thanks also to Ray Brownrigg <Ray.Brownrigg@isor.vuw.ac.nz> who said:

Apparently it is part of the movement towards Solaris or System V
Release 4; a null directory name is treated differently by the kernel.
I can confirm that not following symbolic links in the manner you
describe seems to be a 'feature' of system V. A Silicon Graphics Iris
on our campus behaves the same way.
