Critical Issue: /rewind n rewinds to a wrong number

In a new session, the first time a user runs /rewind n rewinds to the prompt directly before the one included in the command (instead of message 5, message 4 for example). This is undoable using the /rewind undo command, which works fine. Any attempts at rewinding to a specific number, however, are absolutely broken, where any number the user inputs to the /rewind command gets completely discarded and the result is that the chat is rewinded to the message the user rewinded to the first time (in the upper example, after an undo, /rewind 11 would still rewind back to message 4), completely butchering over the chat history and possible the context window of the session. I do see that issue #432 is a duplicate, however the issue still persists and needs another bugfix.

Start by reproducing the behavior in a new session with /rewind n, then use /rewind undo and try a different number. Trace the /rewind command handling and verify that each supplied number selects the requested message rather than reusing the first rewind target. Done means specific rewinds remain correct after undoing and repeating them.
