All the reported bugs have been fixed in RC4 available at t3

Add new options to zs:
-q : quiet option
example: echo "220!" | zs -q > toto
side toto
-m NUMBER : Limit the number of the memory used by the expression evaluator (default is using as much as possible).
Thanks to this new option, you can limit the memory used by zs and have multiple instance of zs in different shells (DIAMOND + Fn works inside zs)
