} After zle .push-line-or-edit both BUFFER and PREBUFFER are empty. Are they
} static values computed on the entry into widget or do they reflect real ZLE
} buffers?

I think they reflect real ZLE buffers.  The "problem" is with the way that
push-input/get-line (and consequently push-line-or-edit) are implemented:
They do something similar to

	print -z "$BUFFER"
	BUFFER=""

and then wait for zle_refresh() to come around and yank the buffer back.
So if you're entirely inside a zle widget (or a bindkey -s), you can't do
anything to the pushed input; it simply isn't there anymore until zsh has
a chance to print a prompt again.
