I checked with gVim 6.4: <C-V>I behaves in same fahsion.
But you can do r{char} with virtualedit=all to fill in whitespace.

Here is a mapping that does this for the `I' command:


xno <script><expr> I mode()=="<C-V>" ? 'Ix<Esc><SID>(sve)gvrxgv"_x<SID>(rve)gvI' : "I"

" set/restore 'virtualedit'
nn <SID>(sve) :<C-U>call <sid>sr_ve(1)<CR>
nn <SID>(rve) :<C-U>call <sid>sr_ve(0)<CR>

func! <sid>sr_ve(save)
if a:save
if &ve != 'all'
let s:save_ve = &ve
set virtualedit=all
endif
elseif exists("s:save_ve")
let &ve = s:save_ve
unlet s:save_ve
endif
endfunc


You may set 'lazyredraw' to reduce visual glitches.
Offhand I don't remember an option to control this, I may be wrong ...
It's just a workaround.
