thanks for reporting that, hallvard! i've extended my patched version
of decode-cgi to cope with that as well:
>> decode-cgi "state=threads&board=cult.tamaraswift&&sort=T"
== [state: "threads" board: "cult.tamaraswift" sort: "T"]
-- snip --
decode-cgi: func [
{Converts CGI argument string to a list of words and value strings.}
args [any-string!] "Starts at first argument word"
/local list nv-pair value name name-chars val
][
add-nv: func [ list name value /local val-ptr ] [
if none? name [ return ]
value: dehex replace/all any [ value (copy "") ] "+" " "
either val-ptr: find list to-set-word name
[ change/only next val-ptr compose [ (first next val-ptr) (value) ] ]
[ append list compose [ (to-set-word name) (value) ] ]
]
list: make block! 8
name-chars: complement charset "&="
nv-pair: [ copy name some name-chars value (add-nv list name val) | "&" ]
value: [ "=" value | "&" | [ copy val to "&" skip | copy val to end ] ]
parse/all args [ some nv-pair | none ]
list
]

if someone wants to submit it to the view 1.3 effort, do not hesitate
to do so.
