I had some trouble but I was able to try ido.el. At first, emacs that
came with cygwin didn't start at all, even when I had X running, so I
downloaded it separately from gnu.org. I installed ido.el directly under
lisp directory, as I don't know how to put it in a user directory. Next
I had trouble understanding how to invoke it. Once I figured out that I
need to use M-x, I was able to try it. See below for my response.

As I explained before, the basic lookup mode is designed to be a lookup
in a full index. However, the plugin comes with a few other means to
lookup, and a generic extension mechanism to add more means. The version
I attached with my previous email includes a new mode which works
similar to ido.el.

This is totally in the control of the new function that I added (see
below for an improved version), and I think it already behaves this way.
It may interpret some characters as filename-wildcards, as recognized by
glob(), so we might need to protect them (but there are not many of
them).

I think all this is covered.

Covered as well.

This can't be done, as I am using the Vim7 completion popup, and it
doesn't support highlighting. However, I worked around by wrapping the
pattern with asterisks (in the new function below), so it kind of works,
though not that easy to read.

Replace the s:LookupWalk function in the plugin/lookupfile.vim with
the one below and try it out. Let me know if this meets your needs. If
you read a bit about Vim scripting basics, you can start playing around
with this function to make the matches look better (e.g, if '/' should
be separate or as part of 'abbr'). See help on |complete-items| on how
the map works.
function! s:LookupWalk(pattern)
" Determine the parent dir.
let parent = matchstr(a:pattern, '^.*/')
let pattern = strpart(a:pattern, len(parent))
let files = glob(parent.((pattern != '') ? '*'.pattern.'*' : '*'))
let fl = split(files, "\<NL>")
let entries = []
for f in fl
let word = isdirectory(f)?f."/":f
let fname = matchstr(f, '[^/]*$')
call add(entries, {
\ 'word': word,
\ 'abbr': fname,
\ 'menu': substitute(fname, '\V'.pattern, '*&*', ''),
\ 'kind': (isdirectory(f)?'/':' '),
\ })
endfor
return entries
endfunction
