That depends on your operating system, on linux it is guided by ulimit
-s (in particular, the argument list is a quarter of the stack size).
On other operating systems, the limit is traditionally quite small.
I'm assuming the above is just an example, but that particular thing
would be better handled by () { echo $# } manyfiles/*, or some
xargs/zargs contraption if you want to be more general.
