I think there's a problem with adding "-" to iskeyword: consider

x-y-z=3

This doesn't work, of course, but the highlighting for it is different 
with "set isk+=-" , and catching the problem is visually easier as is.  
Perhaps changing the regions so that they use  \<for\_s will work (and 
similar constructs for while and until).
