req:required() strips out '+' characters

[bradmann]

This query

let $var := req:required("q", "type=xs:string")
return xdmp:log($var)

with the input
"this is my
++test input"

is stripping out the '+' characters from the input (replacing them with spaces). The characters are being sent across properly url encoded as %2B. Replacing req:required() with xdmp:get-request-field() works correctly.
