  Indeed, it was just popularized by servers calling an extern "ls"
program.

  Server-side globbing is unnecessary, but it helps saving bandwidth.
  On a server with no content summary in a file, it can help to find a file
hidden in subdirectories without the headache of a recursive listing.
  For instance, listing */gnome*.rpm is handy to find that gnome-core.rpm
and gnome-lib.rpm are located in the "gn1" directory.
