Sean Dewar 3a10405214 fix(prompt): prompt_setprompt does not adjust extmarks, no on_bytes
Problem: prompt_setprompt does not adjust extmarks or trigger on_bytes
buffer-updates when fixing the prompt line.

Solution: adjust them, trigger on_bytes.

Notably, hides extmarks when replacing the entire line (and clearing user
input). Otherwise, when just replacing the prompt text, hides extmarks there,
but moves those after (in the user input area) to the correct spot.
