It seemed the least intrusive thing to do at the time. I wasn't sure where
else ML was being used...

My reading of page 700 (which is the sum total of my knowledge of the
subject) is that stroke clears the current PATH so that another stroke
command doesn't include what has already been written out in another line
drawing operation. The receipe given on page 700 would mean that every
underline would be redrawn after each stroke. Clearly we don't want that! I
guess that it leaves the GC in its current state. I agree that putting
stroke into ML would probabally work and would be cleaner.
