Howard, it would have made for a classic LUG portrait if the fork had gone
into the rear element ;-) Enough to spoil your sashimi!
 I have no experience with that particular lens but a leica technician in
Solms told me that "some mindless twisting of the focusing barrel back and
forth" Eek! ;-)
 is likely to accelerate wear and loosen adjustment (in the case of my
Summilux 50). Specifically if you develop any detectable play in the focus
movement, it may cause inaccuracy, for example arriving at the same point of
rotation from different directions may not provide exactly the same point of
focus (visible under more critical conditions).

May or may not be significant for you of course.
YRMMV


Cheers
