I actually prefer this (in .vimrc):

" Show trailing whitespace and spaces before tabs
hi link localWhitespaceError Error
au Syntax * syn match localWhitespaceError /\(\zs\%#\|\s\)\+$/ display
au Syntax * syn match localWhitespaceError / \+\ze\t/ display

It always displays trailing whitespace and spaces-before tabs...  
except if your cursor is at the end of the whitespace.  The updating  
is occasionally a bit laggy (EG: Put spaces on a line and then move  
the cursor off it without pressing <ENTER>), but when you hit Ctrl-L,  
enter, or edit an adjacent line then it updates.

The script mentioned there *is* good for removing said whitespace,  
though
