MAX_ARRLEN

[Peter Stephenson <Peter.Stephenson@csr.com>]

I've just hit MAX_ARRLEN.  The array in question wasn't much larger than
the limit and when I commented out the checks everything just worked fine.
So it looks like an arbitrary limit isn't much use --- no great
surprise, I don't think anyone here is a big fan of them.

What's the right thing to do?  There are various grades ranging from
making it compilable out, through making it compile-time configurable
with an option to compile out, through making it an option to have the
check turned on, to having a variable that we check using getiparam()
each time, to having a special variable so that we don't need to get it
each time.  I think the last option with a clearly named variable such
as ZSH_MAX_ARRAY_LENGTH that can be set to 0 to turn it off is probably
the best.
