I6 lib: fix for L61115 causes problems with DROP etc

I reopened Mantis 977 (inform7.com/mantis/view.php?id=977) because it caused problems with the DROP verb and with interactions with the no_implicit_actions option.

If no_implicit_actions is not true (default), dropping something results in this:

(first taking the cookie)

With no_implicit_actions true, this happens:

What do you want to drop the cookie in?

In any case, this is what should have been printed:

The cookie is already here.

I initially wrote this up as a seperate bug (inform7.com/mantis/view.php?id=1353). Unfortunately I can’t find the notes I wrote on what I was thinking when I came up with that fix. Could I get some help with fixing Mantis 977 (L61115) correctly?
