LGTM. Though it's not clear why you are reducing the length further.

I was thinking to drop the function body all together, i.e. "function foo(arg1,
arg2, arg3) { ...<omitted>... }", since I can't imagine how this is helpful in
error messages.
IMO 128 limit is more than enough to include function name, its arguments and
some code, and saves some clattering comparing to 256.
