Sorry, I meant to try this and then got sidetracked into things like
applying patches.

I assume you're using zsh 3.1, in which case it's not so hard:
probably you need 3.1.6 for the $LASTWIDGET test to work, which is
crucial.  I've called the functions
history-beginning-search-{back,for}ward-end.  If you shorten the
names, you will need to change the pattern matched against
$LASTWIDGET, because the functions need to know that one of the two
was called last, and hence the position to compare up to is already
set.  (Wasted ten minutes wondering why an `if' with a missing `then'
didn't work.  I think we're too lenient with the syntax.)

I might put these in the Functions/Zle directory (after Bart has found out
whatever's wrong with them).


# function history-beginning-search-forward-end {
# history-beginning-search-forward, with cursor at end.

integer ocursor=$CURSOR stat

if [[ $LASTWIDGET = history-beginning-search-(back|for)ward-end ]]; then
  # Last widget called set $hbs_pos.
  CURSOR=$hbs_pos
else
  hbs_pos=$CURSOR
fi

if zle history-beginning-search-forward; then
  # success, go to end of line
  zle end-of-line
else
  # failure, restore position
  CURSOR=$ocursor
  return 1
fi
# }

# function history-beginning-search-backward-end {
# history-beginning-search-backward, with cursor at end.

integer ocursor=$CURSOR stat

if [[ $LASTWIDGET = history-beginning-search-(back|for)ward-end ]]; then
  # Last widget called set $hbs_pos.
  CURSOR=$hbs_pos
else
  hbs_pos=$CURSOR
fi

if zle history-beginning-search-backward; then
  # success, go to end of line
  zle end-of-line
else
  # failure, restore position
  CURSOR=$ocursor
  return 1
fi
# }
