When I have a file opened in a window with the long name, and then I use
:sv or :new with the short name as argument, then both statuslines
display the short name from then on, howsoever I switch windows among
them. Example:

:pwd
/root/.mozilla/seamonkey/nexrdon9.default
:sv ../nexrdon9.default/chrome/userChrome.css
statusline says: ../nexrdon9.default/chrome/userChrome.css
:sv chrome/userChrome.css
_both_ statuslines say: chrome/userChrome.css
Ctrl-W p
both statuslines still say: chrome/userChrome.css

Similarly with
../../seamonkey/nexrdon9.default/chrome/userContent-example.css : as
soon as I supply the short name, _both_ windows for that file get (and
keep) the short name in their statusline.


What happens if you open the file in a window with the short name first,
and then pass expand('%') to MkVimball?


FWIW, I'm using gvim 7.3.661 (Huge) with GTK2-GNOME GUI.


Best regards,
Tony.
