Everything to the left of the cursor at the moment you invoke the search,
but otherwise yes.

} "<what I have on the command line>".

Ah.  Well, zsh doesn't have re-search, though it does recognize "^" as
anchoring to beginning of line.  So you could change one line of the
above to

    else zle .$WIDGET "^$LBUFFER"

Beyond that, try looking at Functions/Zle/incremental-complete-word in the
distribution for ideas of how to implement something more like you want.
Or Functions/Zle/predict-on might be easier to modify -- you'd have to
replace `zle .history-beginning-search-backward' with your own search.
