I have now tried the non-local variable trick, and it works just
like I expected. I also noticed that the zsh completion system
has a set of caching functions (_store_cache, _retrieve_cache and
_cache_invalid). These functions apparently store data on disk,
so that the cache will outlive the zsh session. In my case,
that's problably not good, since running the expensive acroread
-help command is the only way to determine if the cache is invalid,
and thus I will save nothing when using these cache functions.
The version of _acroread that uses a non-local variable is included
below. I would appreciate it someone could tell me who I should
sent it to so that it can be included with the next version of zsh.
(Or better, if that person reads this message, and tells me that
the updated _acroread is now included. :-)
