[ceej] Seems like there are strange things happening with UNDO and "vintage" vim mode.
yep, I've ran into a similar strange clobbered string after searching, changing and using '.' to repeat. At some point, 'u' left me with a garbled string. I curerntly can't repro how I ran into it.
Other issue: entering visual mode with 'v' & 'V' seem now busted, I can only visual select with the non-vim Shift+Up or +Down etc.
Edit: BTW: both issues for me on WS08R2 (using 32bit ST build)
