this patch adds a config option LISTALWAYS that if set, makes 
zsh-4.0.4 always show the complete list if the completion 
resulted in only a partial completion (to help the user decide
what to type next w/o the need for another TAB).

lets say i have a directory with 2 entries:

  opal-3.0.4
  opal-4.0 

my patched zsh will show the following after i type 'cd oTAB'

(%:~/src) cd opal-    
opal-3.0.4/  opal-4.0/

zsh is great. thanks.

jr
