} That turned out to be much less code to implement.  It's attached, if

I like this one.  Is there a mnemonic for your choice of (Y) ?

} I couldn't get it to work via [ -z ]

Hmm, seems to work for me:

torch% print co*
config.h config.log config.modules config.modules.sh config.status
torch% print co*(Y)
config.h
torch% print ba*   
zsh: no matches found: ba*
torch% [ -z ba*(N) ] && echo OK 
OK
torch% [ ! -z ba*(NY) ] && echo OK
torch% [ ! -z co*(NY) ] && echo OK
OK


To zsh-workers:  Any reason not to commit/push this?
