>Subject: [PATCH 1/2] request: handle purple_account_request_password()
>
>This is needed for libpurple plugins with optional password, e.g. SIPE
>since 1.14.1. That libpurple API call boils down to a
>purple_request_fields() call.
>
>The flagging for --enable-leaky-request-stubs was refactored so that
>this new code is always compiled in.
