There are a lot of calls to execute_command that occur in batch-like
places. For example, this is called from Python, I think it is called
from "commands" scripts and "define" scripts, etc.

So if your goal is to have it just emit info at some stopping point, it
seems to me that it would be better to have an observer just before a
prompt is emitted.

I didn't read every patch in detail, so I didn't see where this is used.
Maybe the above doesn't matter.
