Fix vararg operator not being parsed in function arguments.

[Anaminus]

This change modifies the "varlist" function so that it will parse a ... operator that occurs at the end of the variable list. Since varlist is used in multiple contexts, a "funcArgs" argument is added to enforce whether the operator should be parsed.

This change also removes trailing whitespace present in minify.lua.

Commit 1b5254f addresses only part of the problem:

• It still fails if the argument list starts with ..., i.e. the function has only varargs.
• It doesn't prevent the ... "ID" from being localized later, meaning that the vararg symbol gets replaced with an actual identifier. This turns the minified function into a non-vararg one, subsequently causing Lua to choke on any usage of ... within the function body.

I've attempted to correct these issues in #2.

I agree. Closing.
