proxy_pass with variable removes uri

[luckyswede]

Hi,
I've had troubles with url-decoding using this kind configuration, e.g. get
variables with values containing spaces have been decoded before proxied
which is resulting in an error. 
For example I've tried:
location ~ ^/api/(.*) {
    proxy_pass http://api.$host/$1$is_args$args;
}
but that gives an error if the uri is urlencoded.

Any ideas?
