The current command should be saved in a safe place. Then, the necessary
functions (e.g., precmd()) should be called. Finally, the current command
should be restored and displayed with the new prompt(s).

This is not a problem. When the user is typing a command (even if
multiline), the command isn't in the history yet.

Why not?
Or perhaps there should be two different functions: precmd(), which
should behave like now, and preprompt(), which should be run just
before the prompt is (re)displayed. Then, the code that modifies the
prompt should be in preprompt().
