I don't know about your other points, but can give a hint on this
one. The `eshell' takes expressions in Lisp syntax, that means
you have to write `(function arg1 arg2 ...)' instead of the more
customary `function (arg1 arg2 ...)'. In your case:

[1]  (regexp-opt "*.cn" "localhost" "10.0.0.0/8" "127.0.0.0/8" "172.16.0.0/12" 
"192.168.0.0/16")

will lead to the desired result. That's why:

eshell complains here: it is trying to apply a function `".cn"' to the
rest of the arguments. But there is no function with such a funny
name (quotes and all).

Eshell allows you to leave out the outermost parentheses, so instead
of [1] you can also write

[2]  regexp-opt "*.cn" "localhost" "10.0.0.0/8" "127.0.0.0/8" "172.16.0.0/12" 
"192.168.0.0/16"

as a convenience.
