Thanks.  There were also some problems with the removing of ~notauser
words that you suggested:

 > dirs=(${(M)dirs:#~)

Besides the obvious typo of a closing paren for a closing brace, there
are three problems:

1) I want the (R)est, not the match, right?

2) The ~ needs to be escaped, otherwise it'll get expanded.  So what
actually works for me in Zsh-3.1.4 and Zsh-3.0.x is:

3) The pattern after the # needs to match the whole word, so it needs a
trailing *.

echo ${(R)dirs:#\~*}   # words that do not start with ~

#or

echo ${(M)dirs:#/*}    # words that start with /


Thanks again for your pointers and suggestions.  (And thanks to Peter
Stephenson as well!)
