This whole discussion reminds me of some stuff that I always
wanted to clean up a bit...
My _vimhelp still depends on $VIM to be set (parsing "vim
--version" output for vim's fallback for $VIM should be no
problem), and removing sed out of the $vimversion calculation
below could maybe also be done. Anyways... for those who think
this might be useful:

----------------------- _vimhelp ---------------------
#compdef vimhelp gvimhelp

local vimversion curcontext="$curcontext" context state line expl ret tagsfile

vimversion=$(vim --version |& head -1 | sed -e 's/VIM - Vi IMproved //' -e 's/ .*//' -e 's/\.//' -e 's/^/vim/')
tagsfile=$VIM/$vimversion/doc/tags

_vimhelp_update_tags() {
  if (( ! $+_vimhelp_tags )); then
    _vimhelp_tags=(
      $(cat $tagsfile | sed -e 's/	.*//')
    )
  fi
}
_vimhelp() {
   _vimhelp_update_tags
   compadd -- $_vimhelp_tags
}

_vimhelp "$@"
---------------------- / .zshrc --------------------

----------------------- _vimhelp ---------------------
vimhelp () { vim -c "help $1" -c on -c "au! VimEnter *" }
gvimhelp () { gvim -c "help $1" -c on -c "au! VimEnter *" }
---------------------- / .zshrc --------------------

I was once thinking like
   vim -c "h<TAB>
=> vim -c "help
=> vim -c "help Z<TAB>
=> vim -c "help ZZ"
but then I just wrote my little vimhelp wrapper which was easier
to do...

Ciao,
Thomas
