Thanks, Alan.  I remember reading this long thread a while ago, though some of 
the stuff I had trouble following.

Stefan and you are in a better position than I am to assess the significance of 
that issue.  The only data point that I can share is that I've found multiple 
packages to be broken by narrowing, to the point that I don't use narrowing any 
more. Instead, I use a less invasive solution with two invisible overlays 
covering 1..(beginning of narrowed region) and (end of narrowed 
region)..(buffer-size).

Some packages use (point-min) when they really mean 1 (or, if one prefers, 
(save-restriction (widen) (point-min))), and things start breaking in the 
presence of narrowing; so basically, I don't really expect things to work 
smoothly when I use narrowing, and so I don't use it.
