FAQ bug

[Phil Pennock]

In section 2.3 of the new FAQ, the first example of the zsh function for
cd is missing the closing double-quotes:
 cd() { builtin cd "$@; echo $PWD; }

As a thought: Bart pointed out $==* as an alternative to "$@" (one would
almost think he wanted to free up the syntax for something else :^) ...
perhaps mention of this in the FAQ in section 3.1 would be appropriate,
and perhaps mention in the table in 2.3(5), comments section.  I think
the point was more that $* was not always correct and relying on
defaults is a bad idea.  Mentioning both together seems to be one of
those hints that might make the concept of the expansion flags 'click'
in the user's mind.

yup, I've fixed that

There was a problem pointed out by Zoli with $* which still applies to
$==*, namely if you have cd as a function and want to do `cd foo ""'
the null string gets dropped, and it means something completely
different.  There is now a mention of the difference between "$@" and
$* in the shwordsplit section.  I can point out about $==*, if you
don't think it's going to make people's hair stand on end.

Oh good.  That's two things that I've gotten right lately.  Maybe I can
keep up the winning streak.

How about a parenthesised paragraph, along the lines of:
( If you want a simple life, skip this paragraph.  As an example of the
  power of zsh expansion, $==* is $* with shwordsplit explicitly turned
  off for that one expansion, whilst $=* explicitly turns shwordsplit
  on, effectively acting like the Bourne shell's $* )

but reworded to be clearer.  I'm not good at prose.
