port -N reclaim does not remove any ports

[raimue (Rainer Müller)]

When reclaim is started in non-interactive mode with sudo port -N reclaim, the command will check for "unnecessary unrequested ports", but will not remove any of them.

$ sudo port -N reclaim
--->  Checking for unnecessary unrequested ports
Found unrequested ports without requested dependents: qt5-qt3d, grep, grep, gmake, py27-sphinx, py27-sphinx, [...]
--->  Checking for inactive ports
--->  Building list of distfiles still in use
--->  Searching for unused distfiles
--->  Scanning binaries for linking errors
--->  No broken files found.

I expected the command to remove all listed ports without asking me for confirmation, similar to the behavior of commands like port -N install that assume 'yes' as answer in non-interactive mode.
