[Vimperator] :undo not working AND hintmatching=wordstartswith not matching some words as expected

[Harish Varanasi]

Hi,

I recently got introduced to this add-on; it is just fantastic.
Though I am facing a few challenges...

While playing around with a few features, I noticed two issues:

1) :undo or u doesn't seem to undo closed tabs at all
2) :set hintmatching=wordstartswith is not matching words as expected
      Examples:
         a) (Need gvimail plugin) "comma" does not match "Compose
Mail" in gmail.  It should have matched "COMpose MAil"
         b) "roro" does not match "Review: Robot romance `Wall-e'
has heart of gold" in Google News.  It should have matched "RObot
ROmance"

      Otherwise, the matching works in most other cases.

Any ideas?

I am running:
   Vimperator 1.1
   Firefox 3.0 on Windows XP

Thanks,
Harish
