    I'm with you, it's quite logical, but unfortunately people tends
to think that, since a filename is 'linked' to its container
directory, that should affect st_nlink (which is not true, this can
be seen even in the GNU libc documentation). I was not sure if the
standard (POSIX or SuS) specified the opposite.

    Summarizing: Zsh should follow 'find' example and implement tests
for empty dirs investigating its contents, but since this can be
easily done in, let's say, 'user space' (I mean, outside the shell,
using shell commands), I see no need for it. I would like to have a
globbing flag for empty dirs, because it is simpler, better
integrated with the rest of globbin syntax and less error prone, so I
vote for including it O:)
