Yes, something like it.  Currently I managed it so far, that it does redisplay a
line ... with a small problem :-(

Looking in pushlineoredit() I found, that it unconditionally set both
``errflag'' (why?) and ``done''. Obviously, this confused Zle (but I do not know
why). I thought, that I could pass parameter that says "do not set them" - and
here you are! now my small widget really redisplays the input:

(($#PREBUFFER)) && {
zle .push-line-or-edit bla-bla-bla
zle .get-line
zle -R
}

with the sad problem, that it still thinks it is on PS2 and won't return to PS1
(even if I press ^L to redisplay the whole). That is, after

bor@itsrm2:~%> {
cursh> ESC-x foo-widget

I get the following display

bor@itsrm2:~%> {
cursh> {
<= cursor here

and after ^L I get

cursh> {
<= cursor here

Unforunately, here I am lost. I tried it with vanilla push-input/get-line with
the same effect. Obviously, all of them just rely on zleread() to do the work
... sigh.
