Thanks Tim and Andy both!

I'd have figured out :setlocal isk-=\_ myself if I only
had remembered/known the name of 'iskeyword'! I'd
expected 'keywordchars' or somesuch.

This solution is quite ok for me as I need it to work
thus only in individual rw buffers, so that the usual
behavior in help buffers is probably even desirable.
