[armedbear-devel] Support for -- in parameter lists

[Ville Voutilainen]

It's common that a double-dash (--) alone can be used to tell a
command line parser to stop interpreting
further arguments. So, I implemented that very feature for ABCL in
r13226. Lo and behold:

given a test snippet, saved in cmdline.lisp:

(loop
 for item in *command-line-argument-list*
 do (format t "got arg ~a~%" item))

we can do

./abcl --batch --eval '(load "cmdlinetest.lisp")' -- hops hups jee jee
--eval '(format t "hah~%")' -- -- --
