The goal the user has in mind when they are using multibuffer mode and try to open a file is to view (and possibly edit) that file's contents. For that reason, a "nothing happens" outcome from the "File xx is being edited; open anyway?" prompt is the least useful outcome.

So with that in mind, IMHO that prompt and its behaviour should be:

"File xx is already being edited; open in a new buffer?"
Yes -> Open the file in a new buffer.
No -> Switch to the existing buffer for that file, if at all possible (i.e. when it's the current nano process that has locked the file).
Cancel -> Nothing happens.

Rather than the current:

"File xx is being edited; open anyway?"
Yes -> Open the file in a new buffer.
No -> Nothing happens.
Cancel -> Nothing happens.

With the new locking code, trying to open (into a new buffer) a file that nano already has opened, now results in the statusbar message "File being edited (...) continue?"  So you will not accidentally have the same file opened twice.

But I don't like the behaviour when answering No or Cancel: it opens an empty buffer, instead of renouncing the whole opening action entirely.

When using multiple buffers, nano creates a new buffer for each file that I open, even if that file is already open in an existing buffer.

This does not seem like a bug, but more of a usability issue. Many text editors check to see if a file is already "opened" in an existing buffer, if so instead of opening the requested file in a new buffer, switch to the existing one.
