Problem: Unable to see e.g. `inputlist()` prompts that exceed the dialog
window height.
Multi-line prompts are not handled properly, and tracking
is insufficient for messages in cmdline_block mode.
Solution: Add vim.on_key handler while the dialog window is open that
forwards paging keys to the window.
Properly render multi-line prompts. Keep track of both the start
and end of the current cmdline prompt. Append messages after the
current prompt in cmdline_block mode.
